Quick Recap
Israel puts $60M to build their quantum computer. Quantonation in France builds a new $20M fund for their investments in Quantum. In the meantime CQC open sources Tiket and publishes a great work on NLP. Big milestone on programmable photonic chips that could leap frog QCs based in light. Ah, and Barcelona starts implementing its pilot on Quantum Communication link between ICFO and CTTI.
Wait, there is more. This week two papers have made big claims
Fast Factoring Integers by SVP algorithms, while contested, claims that it could break RSA using classical methods.
Simulating the Sycamore quantum supremacy results claims and proves (with code!) that you can simulate classically the same “former advantage” using 60 GPUs and tensor networks.
Basically two papers that could alone take down any quantum supremacy claim, or just help both worlds: classical and quantum computing, keep pushing each other to achieve amazing results
The Quote of the Week
"As the prerogative of Natural Science is to cultivate a taste for observation, so that of Mathematics is, almost from the starting point, to stimulate the faculty of invention."
James Joseph Sylvester - mathematician, inventor of Sylvester's criterion

The Summary of the Week
Paper: Whole-device entanglement in a 65-qubit superconducting quantum computer
The ability to generate large-scale entanglement is an important progenitor of quantum information processing capability in noisy intermediate-scale quantum (NISQ) devices. In this paper, we investigate the extent to which entangled quantum states over large numbers of qubits can be prepared on current superconducting quantum devices. We prepared native graph states on the IBM Quantum 65-qubit ibmq_manhattan device and the 53-qubit ibmq_rochester device and applied quantum readout-error mitigation (QREM). Connected entanglement graphs spanning each of the full devices were detected, indicating whole-device entanglement in both devices. The application of QREM was shown to increase the observed entanglement within all measurements, in particular, the detected number of entangled pairs of qubits found within ibmq_rochester increased from 31 to 56 of the total 58 connected pairs. The results of this work indicate full entanglement in two of the largest superconducting devices to date.

GlaxoSmithKline Marks Quantum Progress with D-Wave
The mRNA codon optimization problem is a good fit for quantum annealing because it is an NP-hard optimization problem—the very problem set D-Wave has often discussed when describing potential use cases. In this problem each amino acid in a protein sequence can be represented by as many as six codons, the goal is to find the right combination. This problem is important because, as the authors of the GSK paper on codon optimization on quantum architectures note, it can “impact downstream processes such as protein folding and function, which is important for use cases including recombinant protein therapies.”
