Quantum 7, 1201 (2023). https://doi.org/10.22331/q-2023-12-06-1201 In this work, we apply the advantage distillation method to improve the performance of a practical twin-field quantum key distribution system under collective attack. Compared with the previous analysis result […]
Insider Brief Multiverse Computing and Moody’s Analytics to launch a Software as a Service (SaaS) platform that provides a marketplace for quantum-based solutions. The team leading the initiative will work with key Moody’s clients and […]
Multiverse Computing, in collaboration with Moody’s Analytics, has launched QFStudio, a Software as a Service (SaaS) platform. This initiative, announced in San Sebastián, Spain, combines Multiverse’s expertise in quantum algorithms with Moody’s extensive experience in […]
Quantum 7, 1200 (2023). https://doi.org/10.22331/q-2023-12-06-1200 We study the entanglement dynamics of quantum automaton (QA) circuits in the presence of U(1) symmetry. We find that the second Rényi entropy grows diffusively with a logarithmic correction as […]
Quantum 7, 1199 (2023). https://doi.org/10.22331/q-2023-12-06-1199 The device-independent framework constitutes the most pragmatic approach to quantum protocols that does not put any trust in their implementations. It requires all claims, about e.g. security, to be made […]
Insider Brief Quantacet is a new venture capital fund based in Quebec and dedicated to quantum technology startups. The group announced its first closing of a $20 million. Contributors include the Quebec government, through its […]
Quantum 7, 1198 (2023). https://doi.org/10.22331/q-2023-12-06-1198 Bosonic cat qubits stabilized by two-photon driven dissipation benefit from exponential suppression of bit-flip errors and an extensive set of gates preserving this protection. These properties make them promising building […]
I was at the Q2B quantum Computer conference today and there was a talk about NSM-10 and the change of the encryption that underlies global finance and data protection. In 2024, the US government will […]
Once again, the Unitary Fund has surveyed a wide variety of users to help the industry gain a better understanding of the who the users are, what tools and software they are using, and the […]
JP Morgan is working to apply all kinds of quantum systems with all kinds of quantum hardware. They have proved different clear academic examples of speedup over classical systems with quantum systems. However, it is […]
