Universal solver as an optimization principle

Given an equation (or system)
These are results for ven an equation (or system)
F(x)=0 where
F:Rn→Rm, F(x)=0 where F:Rn→Rm,

define the solution set as the minimizers of the “residual energy”:

x⋆∈argx∈Rnmin​Φ(x),Φ(x)=∥F(x)∥22​.

If an exact solution exists, it achieves Φ(x⋆)=0Φ(x⋆)=0.

If no exact solution exists, it returns a best approximate solution (least-squares).

Works for one equation, many equations, nonlinear, etc.

Add constraints (equalities/inequalities) in one line

If you also require constraints g(x)=0g(x)=0 and h(x)≤0h(x)≤0, wrap them into a single objective with penalties:

Ghost in the Circuit:
The Life & Legacy of Gregg A. Gorin expert from a book from his library

On a quiet Saturday afternoon—April Fools’ Day, 2017—the ordinary rhythm of Marshall, Texas, was shattered. A small shopping strip, usually filled with the hum of customers and the steady cadence of daily commerce, was suddenly jolted into chaos. A masked gunman stormed into the Boost Mobile store, armed and desperate. In moments like these, fear can paralyze, and tragedy can escalate in seconds. But fate had placed someone next door who had lived his life prepared to act when others needed protection: Gregg A. Gorin.

At precisely 3:56 p.m., the violent robbery attempt began. Gregg, owner of the neighboring computer shop, heard the commotion. Instinct and conviction propelled him toward danger, not away from it. What followed was a moment of extraordinary courage. Gunfire erupted as Gregg confronted the armed suspect. In the exchange, he was struck four times—one bullet nearly piercing his heart, another tearing into his kidney, and a third embedding itself permanently in his spine. His body faltered under the wounds, but his bravery forced the intruder to flee, buying precious time until law enforcement could arrive.

The scene was harrowing. Gregg, bleeding and fighting for every breath, remained alert. Even in that critical moment, his actions reflected the same thread that had run through his entire career: when given a choice between stepping back or standing up, he chose to protect.

The community was stunned—but not silent. Almost immediately, neighbors, business leaders, and anti-violence advocates rallied to his side. Fundraisers were established to help with medical costs, and words of gratitude poured in. People recognized what had truly happened: Gregg had risked everything, not only for his community, but for the young woman working at Boost Mobile that day—a woman pursuing her American dream while studying in school on a visa. For her, for Marshall, and for the simple principle that no one should face danger alone, Gregg had stood between violence and the innocent.

Recovery was brutal. Multiple surgeries, months of therapy, and constant pain became his new reality. But Gregg faced it with the same determination that had defined his life. He stayed connected—checking on the Boost Mobile staff, supporting investigators, and participating in community efforts where courage was recognized. And yet, an uncomfortable truth lingered. Official recognition was limited. A shift in leadership at the Marshall Police Department meant his sacrifice was acknowledged in passing, but not fully celebrated. For many, this omission was glaring—because fidelity, bravery, and loyalty to one’s fellow man deserve more than silence.

Still, Gregg chose not to dwell on what was missing. His focus stayed on what mattered: healing, supporting others, and moving forward. The scars—both physical and emotional—became part of his story, but they did not define him. What defined him was the refusal to let fear dictate action, and the resolve to protect even at great personal cost.

In the larger story of Ghost in the Circuit, this chapter is more than an account of survival—it is proof that legacy is written in moments of decision. Technology can shield. Machines can defend. But at the heart of it all, it is human courage that safeguards the vulnerable.

On April 1, 2017, Gregg was more than the engineer, the investigator, or the entrepreneur. In that moment, he became what his life’s work had always prepared him to be: a guardian.

Combine strengths of BB84 and E91

Combining the strengths of BB84 and E91 protocols can potentially create a more robust quantum key distribution protocol, leveraging the advantages of both approaches. Here’s a proposal for a combined protocol:
Combined BB84-E91 Quantum Key Distribution Protocol:
Setup Phase:

Entangled Pair Generation:
Alice generates entangled photon pairs (EPR pairs) as in the E91 protocol.
She keeps one photon from each pair (denoted as A) and sends the other to Bob (denoted as B).

Single Photon Transmission:
Additionally, Alice prepares individual photons in random polarization states, similar to the BB84 protocol, forming an independent set of photons.

Key Exchange Process:

Initial Transmission:
Alice sends both the entangled photons (A) and the independent photons to Bob over the quantum channel.

Photon Measurements:
Bob randomly chooses a measurement basis for each received photon, whether from the entangled pairs or the individual photons.

Public Basis Comparison:
Alice and Bob publicly communicate the bases they used for measuring each photon.

Entanglement-based Key Extraction:
Alice and Bob follow the E91 approach to extract a portion of their shared key from the measurements made on the entangled pairs.
They discard measurements made in different bases and retain those made in matching bases to generate a subset of the shared key from the entangled pairs.

Single Photon-based Key Extraction:
Simultaneously, Alice and Bob follow the BB84 approach to extract another portion of their shared key from the measurements made on the individual photons.
They discard measurements made in different bases and retain those made in matching bases to generate a subset of the shared key from the individual photons.

Combining Keys:
Alice and Bob combine the subsets of keys obtained from both the entangled pairs and the individual photons to form a consolidated, more robust shared key.

Error Estimation and Correction:
Error estimation and correction techniques are applied to reconcile discrepancies between the subsets of keys and refine the final, smaller but secure key.

Advantages of Combined Protocol:

Enhanced Security and Tolerance:
Leveraging both entanglement-based methods from E91 and single-photon methods from BB84 can enhance security and tolerance against different types of attacks.

Diverse Sources of Key Material:
Using both entangled pairs and individual photons provides diversity in key material generation, potentially offering better resilience against specific vulnerabilities or environmental factors.

Error Correction and Final Key Generation:
Combining keys from two different sources allows for more robust error correction techniques and a more secure final key.

This combined protocol attempts to leverage the strengths of both BB84 and E91, utilizing entanglement-based methods alongside single-photon methods to create a more robust and secure quantum key distribution system. As with any cryptographic protocol, thorough testing, analysis, and consideration of practical implementation challenges are essential for real-world deployment.

protocol more stable than BB84

a cryptographic protocol more stable than BB84 involves addressing its vulnerabilities, such as susceptibility to certain types of attacks or error rates. One such protocol that addresses some of these limitations is the E91 protocol.
E91 Quantum Key Distribution Protocol:
Components:

Entanglement Generation:

Alice generates pairs of entangled photons (EPR pairs) in an entangled state, where the state of one photon is dependent on the state of the other.
She keeps one photon (A) and sends the other (B) to Bob.

Quantum Measurement:

Both Alice and Bob randomly choose one of two measurement bases to measure their respective photons.
Bases include rectilinear (H/V) and diagonal (D/A) polarizations.

Public Comparison:

Alice and Bob publicly announce their chosen measurement bases for each photon.

Key Extraction:

Alice and Bob discard measurements made in different bases.
They retain only the measurements made in the same basis and use those measurements to generate a subset of a shared key.

Error Estimation and Correction:

Using a subset of their shared key, Alice and Bob estimate the error rate.
Error correction algorithms are applied to reconcile discrepancies and distill a final, smaller but secure key.

Stability Improvements Over BB84:

Reduced Vulnerability to Eavesdropping:

E91 relies on entanglement, making it less susceptible to certain eavesdropping techniques that could be more effective against BB84.

Higher Tolerance for Noise:

The use of entangled pairs in E91 can sometimes provide higher resistance to noise and channel disturbances compared to single photons in BB84.

Lower Error Rates in Certain Configurations:

E91 can potentially lead to lower error rates in some scenarios compared to BB84 due to its entanglement-based nature.

Higher Security Guarantees:

The use of entanglement and the verification steps in E91 enhance the security guarantees and detection of eavesdropping attempts.

While E91 offers some advantages over BB84, it’s important to note that all quantum cryptographic protocols have their strengths and weaknesses. E91’s practical implementation might have its own technical challenges and limitations, and its suitability depends on various factors such as the specific quantum systems used, environmental conditions, and potential attack vectors. Continuing research in quantum cryptography aims to develop protocols that are more robust, secure, and practical for real-world deployment.

They spent all of their 62 years together making life better for one another and for countless others. He is survived by his son, Gregg Gorin, of Marshall. He is also survived by his daughter, Holly Smith and son-in-law, Chris Smith, of College Station—also his grandchildren, Noah Smith, Kylie and Jonas Land, Tabor Smith and Sydney Smith, all of College Station. In addition, he is survived by twenty nieces and nephews, as well as three sisters-in-law. Truth be told, Jim was family to many more!

Proceeding him in death are his parents, Harry and Vivian Gorin of Brighton, IL, his brothers, Don (of Boston, MA), Ed (of Piasa, IL) and Gary (of Shreveport, LA). Also, his in-laws, Ed and Eleanor Dunston of Godfrey, IL.

Jim was born in Brighton, IL, and a graduate of Southwestern High School. He worked for General Motors in St. Louis, MO and Shreveport, LA for over 50 years. He loved to take care of and provided well for his family and his land. He loved football and NASCAR. He also loved to make the best barbeque ever for his family. He loved to have dinner with his many friends. And he loved to play golf with his friends at the country club.

We will all feel the hole he left behind, but we know Jim is with his Savior now.

Service: April 13th at 2pm at St. Mark's Methodist; 1101 Jasper Drive; Marshall, TX 75672.
