Clearly, It’s Been Explained.

Quantum computing, quantum mechanics, quantum bits, and so on. Quantum is one term many people shy away from at its mere mention. However, as quantum computers make the mainstream news more often, some of us (Qubit included), have been trying to grasp the concepts and convey them in layperson’s terms. This piece makes an attempt to expose quantum computing and topological qubits in a crisp, clear light. Well worth sinking a few minutes into to gain some understanding or give some understanding as you see fit. May 1, 2018.

“C” is for “Commutative”

This past week, cryptologists from Belgium and The Netherlands released a report on a post-quantum computing algorithm promising quantum resistance. The claim is the algorithm provides a non-interactive key exchange while similar in construct to common elliptic curve cryptosystems (ECCs). This commutative, super-singular elliptic-curve, is touted as being able to be “dropped-in” to replace instantiations of quantum-vulnerable ECCs while maintaining quantum-resistant security schemes. Read the researcher’s report on this scheme dubbed “Commutative Super-singular Isogeny Diffie-Hellman” (CSIDH). May 1, 2018.

Quantum Key Distribution Takes a Sizeable Step

Twin-field quantum key distribution (TF-QKD) has been publicly announced by a team of scientists from Toshiba Research in the U.K. Seeking to extend the range of QKDs with an improvement in bandwidth. Simply, a quantum repeater is placed between two communicating parties. Both parties send their code to the repeater which then relays measurements of the entangled signals. From this, the two parties produce a key known only to them. An interesting and plausible concept albeit just that, for now. Quantum is coming. May 3, 2018.

Works in Ambient Room Temps, Easy to Make, Thin.

German physicists, using thin semiconductors as targets of infrared lasers have shown how to excite electrons between the 1 and the 0 classical states. The speed of these shifts is an astounding one million times faster classical computing. Doing such state changes so rapidly permits processing prior to losing the fragile state; put another way, the quantum state does not need to be retained for an extended period to gain benefits from processing. Much effort is being placed in developing quantum computing systems which are free of external influences such as heat and magnetism. The method shows much promise as it holds benefits which include use in ambient temperatures, thin, atomic-thickness layers of material, and an overall simplicity in construction. Read on.

Packets of Energy; Subtractable, Indivisible

Teams at the University of Southern Denmark, Arhaus University, and the University of Maryland’s Joint Quantum Institute have demonstrated the ability to subtract a photon of light from a laser beam. A unique property of light is its non-interaction with other photons as they pass through one-another. This property benefits quantum communication with high-success rates of transmission over long distances with encoded data. The study’s goal is to manipulate photons using other photons; causing photons to interact with one-another. The benefit lays within photon-photon interaction as it pertains to quantum information science. The team admits there is much study to complete to fully understand these interactions. May 14, 2018.

Quantum Many-Body Scars

Using precision laser instrumentation, recent work by Harvard and MIT discovered atom chains oscillating beyond reasonable expectations. An explanation has been offered by researchers from the University of Leeds and others. The observed phenomenon has been labeled as “quantum many-body scars”. The end-effects observed are chains of atoms not filling their entire chaotic-space as one would expect — a quantum scar. The thought is the atoms retain quantum qualities longer than expected.

Entangled Clouds

Faculty at the University of Hannover have created two clouds of entangled atoms. Different from entangled atomic particles as earlier efforts created, the clouds of atoms were “Bose-Einstein condensates”. These atomic condensates were effectively occupying the same position in a coherent state; considered entangled. Separating the two clouds permitted the team to demonstrate the entangled quality. At present, large scale quantum computing is held back due to lack of needed scale in entangling particles. This could be a valuable step in the large scale quantum computing direction.

Intel ~10 Years; Microsoft ~5 Years; IBM ~5 Years

Intel is one of the forerunners in the race to quantum supremacy. Alongside Microsoft, IBM, and Google, Intel hopes to press on to success with its silicon-based quantum processors. Doing so would be ideal as Intel is the world leader in silicon chip manufacturing for classical computers. If able to create quantum supremacy with silicon chips, they have the infrastructure to mass produce the wafers and the proven history and intellectual property to do so effectively. James Clarke, Intel’s director of hardware, believes maturity for quantum computing will have to wait a decade.

TLS 2.0

Forward Secrecy’s use as a layer of security during encrypted sessions may be threatened. Simply, Forward Secrecy permits only the end-points in a secure session to decrypt traffic.

Device-Independent Quantum Key Distribution

With attempts to establish cybersecurity in every aspect of our connected world struggling to succeed, quantum computing may arrive before true information security is established.

Is Cryptographic Agility The Solution?

In the next ten years, the notion of quantum supremacy will have likely been attained, and further, quantum computing will have begun to crack data encryption of the prolific types in use today. Ten years. Who knows of this impending shift from “security” to seemingly instant “insecurity”? Even data encrypted today, last week, 3 years ago, etc., will be vulnerable to decryption. Is anyone listening? Ten years, if predictions hold firm. There are some industry leaders – IBM, for one – which believe the time before quantum supremacy and its deleterious effects upon encryption are a mere 5 years in the offing.

“Computationally Infeasible”

The hub-bub to-do with quantum computers and encryption lays in the computational difference between the quantum and the classical computer processing power. Today’s confidentiality for data-in-transit across the internet relies upon the computational infeasibility of cracking the encryption. (It would take too long to break the code with classical computers). The advent of quantum computing will significantly reduce the time to crack the encryption codes. Quantum key distribution (QKD), a method of distributing secret keys between two parties, is possible – today – in enabling perfect secrecy between two-parties.
