The Week in Quantum Computing - February 20th
Issue #126
The Week in Quantum Computing. Brought to you by Sergio Gago (@piratecto).
Quick Recap
UNSW Sydney researchers developed a new type of quantum bit called "flip-flop" qubit in silicon, which can be used to build a large-scale quantum computer. Researchers at the Kastler Brossel Laboratory built the first converter between two different types of quantum-bit encodings to bridge the gap between different platforms for quantum computing. Quantum Brilliance secured $18 million USD in funding to advance miniaturized quantum computers. Thales and Quantinuum offered a trusted foundation to help organizations begin creating quantum resilience today. Quantinuum also changed their CEO naming Rajeeb Hazra, a heavy weight in the HPC industry. Together with Rigetti’s shakeup and D-waves cash issues published last week, investors are getting nervous due to a general downturn in the tech market, causing some companies to freeze headcount or experience layoffs. Finally, Alice & Bob published a paper showing that a 256-bit elliptic curve logarithm can be computed in 9 hours with 126,133 using their “cat” qubits. Additionally, an article discussed how the Chinese government is collecting as much data as possible, both encrypted and unencrypted, in anticipation of the coming era of quantum computing

Quantum Computers: What Is Q-Day? And What’s the Solution?
“Think of China’s spy balloon as a giant vacuum sucking up all communications in its path. Encryption protects us, right? Wrong. The Chinese government is collecting as much data as possible — both encrypted and unencrypted — because of the coming era of quantum computing.”

The 'flip-flop' qubit: realisation of a new quantum bit in silicon controlled by electric signals
UNSW Sydney research demonstrates a new type of quantum bit in silicon, called ‘flip-flop’ qubit, which can facilitate the construction of a large-scale quantum computer. “Sometimes new qubits, or new modes of operations, are discovered by lucky accident.

Quantum data conversion offers a path to scale up quantum technology architectures
Researchers at the Kastler Brossel Laboratory in Paris have succeeded in building the first converter between the two different types of quantum-bit encodings—an equivalent to converters for classical information, but targeted to different types of quantum data. This high-quality rewriting of information shows the way towards bridging the gap between the many different platforms competing in the race for quantum computing and may enable the interconnectivity of future networks.

blueqat: No-Code QAOA & Annealing
This article isn’t a thorough review, mostly because blueqat’s user interfaces are so straightforward. Seriously, you just provide a QUBO and click a button. Maybe they just have educational value. Maybe you can do more with them than that.

Quantinuum Names Rajeeb (Raj) Hazra Chief Executive Officer
Quantinuum further strengthens its management and leadership team as it extends its global leadership position. Hazra will help Quantinuum, the largest standalone integrated quantum computing company in the world, in its mission to accelerate quantum computing as it enters a period of rapid scaling. Current CEO and founder Ilyas Khan remains in the leadership team and will focus on product development and innovation as Chief Product Officer. He also remains a member of Quantinuum’s board of directors and will take up the position of Vice Chairman.

Thales and Quantinuum Offer a Trusted Foundation to Help Organizations Begin Creating Quantum Resilience Today
Key generation is an essential part of the encryption layer in any cybersecurity implementation, but organizations must also consistently and reliably safeguard their cryptographic assets, including keys, certificates, and other cryptographic tokens. Hardware Security Modules (HSMs) such as the Thales Luna HSM offer an appealing solution in this case.

Frostbite Comes to Quantum; Layoffs at Rigetti, Reported Cash Crunch at D-Wave, and Headcount Freezes in Other Companies
We have said for a long time that we do not expect there will be a Quantum Winter, but quantum in 2023 will be an uneven market with some companies getting frostbite. After several years of great expectations for quantum, investors are getting nervous and being a lot more cautious about making investments. And the overall tech environment hasn’t been helped by the general downturn we are seeing in tech right now.

Computing 256-bit elliptic curve logarithm in 9 hours with 126,133 cat qubits
Many envisioned applications of quantum computing (quantum dynamics, quantum chemistry, financial optimization, …) require a large-scale quantum computer – typically composed of a few thousands of qubits and the ability to run quantum gates [2-4]. Running such algorithms is well beyond the capabilities of the quantum hardware, which is currently in the range of a few hundreds to a few thousands of noisy qubits (with error rate in the range for the best hardware, allowing to run only up to a few thousand quantum gates). Although the theory of fault-tolerant quantum computing (FTQC) solves this issue, operating a quantum error correcting code (QECC) below its accuracy threshold remains challenging experimentally, and this strategy comes with an important hardware overhead (say, the number of qubits), such that building a fault-tolerant quantum computer at scale (composed of millions of qubits) is a daunting engineering task.

NISQ Is Dead, a Dying Dead End, With No Prospects for a Brighter Future or Practical Quantum…
This is just a final note on my decision to abandon NISQ approaches to quantum computing as well as full quantum error correction (QEC), in favor of advancing to low-noise or what I call near-perfect qubits and post-NISQ quantum computing, as well as full any to any qubit connectivity and quantum pr

It's time to prepare for quantum computing’s impact on DNS security
Mainstream quantum computing may still be years away, but cybersecurity efforts to protect against quantum attacks can’t wait. When quantum computing does make its entrance, it could quickly eviscerate the cryptography that currently protects online communications, such as the digital signatures used in the domain name system (DNS) and the key exchanges used in transport layer security (TLS).

Paper: Performance analysis of quantum repeaters enabled by deterministically generated photonic graph states
By encoding logical qubits into specific types of photonic graph states, one can realize quantum repeaters that enable fast entanglement distribution rates approaching classical communication. However, the generation of these photonic graph states requires a formidable resource overhead using traditional approaches based on linear optics. Overcoming this challenge, a number of new schemes have been proposed that employ quantum emitters to deterministically generate photonic graph states. Although these schemes have the potential to significantly reduce the resource cost, a systematic comparison of the repeater performance among different encodings and different generation schemes is lacking. Here, we quantitatively analyze the performance of quantum repeaters based on two different graph states, i.e. the tree graph states and the repeater graph states. For both states, we compare the performance between two generation schemes, one based on a single quantum emitter coupled to ancillary matter qubits, and one based on a single quantum emitter coupled to a delayed feedback. We identify the numerically optimal scheme at different system parameters. Our analysis provides a clear guideline on the selection of the generation scheme for graph-state-based quantum repeaters, and lays out the parameter requirements for future experimental realizations of different schemes.
