The Week in Quantum Computing. Brought to you by Sergio Gago (@piratecto).
Quick Recap
Oh my god. 150 editions of the Newsletter. THANK YOU very much for your continuous support and to all the new readers coming every week.
QuEra Computing has responded to surging demand by quadrupling the availability of its Aquila quantum computer on Amazon Braket. Quantum Machines unveiled the OPX1000, a quantum controller with the capacity to manage over 1,000 qubits, marking a significant leap in scaling quantum hardware. IQM Quantum Computers is democratizing quantum access with "IQM Spark," a quantum computing solution aimed at universities and research labs. It includes a 5-qubit quantum processing unit, fostering quantum exploration and experimentation among academic and scientific communities (democratizing as long as you have 1M€ available). In the quest to validate quantum computational advantage reliably, researchers at NIST, UC Berkeley, Caltech, and other institutions introduced a novel protocol that leverages mid-circuit measurements and cryptographic techniques. Finally, SK Telecom is taking a proactive role in developing international standards for quantum-safe communication, ensuring the security of data transmission in the age of quantum technology. NIST released another factsheet for PQC adoption. A qubit based on Lorenz attractors has been proposed, and a fantastic conversation on the quantum stack overflow about D-wave’s advantage claims.

The Week in Quantum Computing
Who’s afraid of quantum technology?
The road to a quantum future may be longer and more winding than some expect, but the potential it holds is profound. If the Sydney Harbour Bridge was rebuilt today engineers would design, build and test the new bridge in virtual worlds before a sod of dirt was turned.

QuEra Quadruples Availability of its Quantum Computer on Amazon Braket
QuEra Computing, maker of the world’s first and only publicly-accessible neutral-atom quantum computer – Aquila, today announced an increase in the availability of the device from 10 to 48 hours per week on Amazon Braket, a fully managed quantum computing service from Amazon Web Services. This expansion in capacity is in response to a consistently high level of customer demand and makes it even more convenient for customers around the world to utilize Aquila in their respective time zones.

Quantum Machines’ next-gen quantum control solution that can scale beyond 1,000 qubits
Tel Aviv-based Quantum Machines today announced the OPX1000, the latest iteration of its quantum controller. Built for large-scale quantum computers, the OPX1000 can control 1,000 qubits and more, well beyond what its predecessors the OPX and OPX+ controllers could handle.

Video: How ORCA Computing's photonic quantum computers work
Rack-mounted, room temperature and leveraging off-the-shelf, telecoms-grade optical fibre components, ORCA Computing's PT Series provides access to quantum computing capabilities now. It is ideally suited for integration into classical computing infrastructure and workflows.

Quantum supremacy explained
Over the past several years, there have been tremendous advances in the field of quantum computation, but even greater amounts of hype surrounding those advances.
A few years ago, quantum supremacy was achieved for the first time, where a quantum computer performed a calculation millions of times faster and more efficiently than a classical computer.
But that's a far cry from many of the technological advances being promised, including achieving quantum supremacy for a single practical problem. Here's how to separate fact vs. fiction.

A new protocol to reliably demonstrate quantum computational advantage
To reliably demonstrate that a quantum computer performs better than a classical computer, one should, among other things, collect precise measurements inside the computer and compare them to those collected in classical computers. Doing this, however, can sometimes be challenging, due to the distinct nature of these two types of devices.
Researchers at NIST/University of Maryland, UC Berkeley, Caltech and other institutes in the United States recently introduced and tested a new protocol that could help to reliably validate the advantage of quantum computers. This protocol, introduced in Nature Physics, relies on mid-circuit measurements and a cryptographic technique.

Proposal for a Lorenz qubit
Nonlinear qubit master equations have recently been shown to exhibit rich dynamical phenomena such as period doubling, Hopf bifurcation, and strange attractors usually associated with classical nonlinear systems. Here we investigate nonlinear qubit models that support tunable Lorenz attractors.

How Quantum Computing Will Impact Cybersecurity
Quantum computers live in research universities, government offices, and leading scientific companies and, except in rare circumstances, find themselves out of reach of bad actors. That may not always be the case, though.

How would room-temperature superconductors change science?
The wave of excitement caused by LK-99 — the purple crystal that was going to change the world — has now died down after studies showed it wasn’t a superconductor. But a question remains: would a true room-temperature superconductor be revolutionary?
The answer is that it depends — on the application, and on whether the hypothetical material also has other crucial qualities. But at least in some scientific fields, in particular those that use strong magnetic fields, better superconductors would be likely to have a huge impact.

Did D-Wave show quantum advantage in 2023?
Google's quantum group demonstrated quantum advantage with a much earlier version of D-Wave hardware in the following figure from a 2016 paper, in which the D-Wave hardware found the ground state of Ising (spin glass) Hamiltonians involving up to 945 spins/qubits, about 7 orders of magnitude faster
