Hello Everyone,

At the Quantum Foundry (archives), there are times when I seek to try to learn something a bit off the beaten track. If there ever comes a time when Quantum computing is a bit more mainstream, I’d really want to do more than startup deep dives, products, partnerships but and also more educational pieces.

In a nutshell, Quantum Teleportation: is a technique for transferring quantum information from a sender at one location to a receiver some distance away. China has been especially interested in this concept.

As China becomes more interested in Space technology, their Quantum teleportation, simulation and sensing technologies truly do become world class and useful in ways we as a species are only starting to fully discover in the 2020s.

Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lami from the University of Amsterdam have shown, through probabilistic calculations, that there is indeed, as had been hypothesized, a rule of entropy for the phenomenon of quantum entanglement. Our understanding of Quantum Entanglement continues to evolve.

Quantum Entanglement is a physical phenomenon that occurs when, in two or more particles, the quantum state of each particle cannot be described independently of the state of the others, including even when the particles are separated by a large distance.

Quantum teleportation usually relies on perfectly connected pairs of particles (entangled qubits), but it’s easily messed up by decoherence, which disrupts those connections.

Teleportation in Noisy Environments

Researchers at the University of Turku, Finland, and the University of Science and Technology of China, Hefei, have proposed a unique solution to overcome this problem. The novel method allows for high-quality teleportation to occur even in noisy environments.

“The work is based on an idea of distributing entanglement — before running the teleportation protocol — beyond the used qubits, i.e., exploiting the hybrid entanglement between different physical degrees of freedom”, said Jyrki Piilo, a professor at the University of Turku, in a statement.

The details of the team’s research were published in the journal Science Advances.

So this is a bit counter-intuitive. The teleportation protocol traditionally fails in the face of noise with typical qubit entanglement and in the scenario where hybrid entanglement and silence are present at first.

“However, when we have hybrid entanglement and add noise, the teleportation, and quantum state transfer occur in an almost perfect manner”, said Olli Siltanen, whose doctoral dissertation presented the theoretical part of the current research. See the LinkedIn post here.

Hey Everyone,

Just a quick update. I noticed Quantum computing related company Zapata AI is going public via its SPAC.

The shareholder approval comes a little over two weeks after the Securities and Exchange Commission had declared the Form S-4 for the proposed merger “effective,” clearing the path for the deal to proceed.

Two key members of the SPAC’s m…

Hey Everyone,

I want to dabble in some recent research and product map launches.

Quantinuum is a quantum computing company formed by the merger of Cambridge Quantum and Honeywell Quantum Solutions. In many ways they are among the leaders in Quantum computing innovation.

It’s always amusing to see how brands even define what Quantum computing is:

I’m fairly curious how Quantum computing and Generative AI are going to meet and intersect. Recently on January 11th, 2024 Quantinuum announced some research that is possibly related.

🌌 Quantum Natural Language Processing

For the first time, Quantinuum researchers have run scalable quantum natural language processing (QNLP) models, able to parse and process real-world data, on a quantum computer. In a recent paper, the researchers define machine learning models for the task of classifying sequences – which can be anything from sentences in natural language, like movie reviews, to bioinformatic strings, like DNA sequences.

This paper shows us that we can run, train, and deploy QNLP models on present-day quantum computers.

This paper shows us that we can run, train, and deploy QNLP models on present-day quantum computers. When compared to neural-network-based classifiers, the quantum model does just as well on this task in terms of prediction accuracy.

So how might fault-tolerant Quantum computing in the future impact Machine learning?

Welcome back!

I’m debating covering more science news on Quantum Foundry and the main reason has to be the lack of exciting new Quantum computing startups I usually cover. So you might expect a sampling of:

• Biotechnology

• Space and Cosmology News

• Science News

• Physics

• Longevity

• Exponential technologies of the future

• Emerging Tech, and so forth.

Recently there was a story that got my attention. A scientific breakthrough being hailed as "one of the holy grails of modern physics" is also raising some eyebrows. 2023 has been a year of major hype for Generative A.I., but also the usual PR for quantum computing being “close” and “AGI” being just around the corner. So what is up with the holy grail of superconducting?

A team of researchers claims to have created the first materials that conduct electricity perfectly at room temperature and ambient pressure, but many physicists are highly sceptical.

In recent days, many commentators have become excited by two papers that claim to document the production of a new superconductor that works at room temperature and ambient pressure.

South Korea?

Scientists in Korea said they had synthesised a new material called LK-99 that would represent one of the biggest physics breakthroughs of recent decades. The fact that some previous reports of breakthroughs in superconductivity were later retracted and that other teams failed to replicate the results also raises the stakes.

There’s not a week that goes by that I don’t read several posts about “Quantum breakthroughs”, so I think we need to start from a grounding of healthy skepticism. I don’t personally believe in miracles. Unless we are talking genuinely reverse-engineering alien tech. UAP stands for "unidentified anomalous phenomena," a catch-all term to describe objects detected in the air, sea and space that defy easy explanation. 2023 has been a major year for that in the public eye, but that’s another story.

Creating a material that perfectly conducts electricity at room temperature and pressure would be a big deal, but a research team's claims of creating one has attracted more scrutiny than optimism

• LK-99 could be a watershed discovery that enables widespread maglev trains and quantum computers, or it could be another major disappointment.

The First Room-Temperature Ambient-Pressure Superconductor

Submitted July 22nd, 2023.

• Lossless electricity transmission through power grids
  * Magnetically levitating vehicles
  * A new generation of high field magnets for MRI scanners
  
  and closer to my current interests,
  * Superconducting filters in telecom cell sites for better signal quality
  * Room temperature processors for Quantum computers
  ... all without the need for cryogenic cooling.

Still it’s fun to hope that emerging tech is on a fast-track with new breakthroughs around nearly every corner. Could this actuallys signal a new era of superconductivity?
