Problems requiring optimization are widely prevalent in the financial industry and there are several quantum approaches that are being researched to provide a quantum advantage over the classical techniques commonly used today. Terra Quantum and […]
Cri/oFlex® I/O Module for a Quantum Computer. Credit: Delft Circuits A large portion of Delft’s Circuits’ Series A funding came from new investor DeepTechVC which supplied €5 million. The remainder came from their previous seed […]
Researchers from the RIKEN Center for Quantum Computing have used machine learning to perform error correction for quantum computers—a crucial step for making these devices practical—using an autonomous correction system that despite being approximate, can […]
Insider Brief Terra Quantum and HSBC will collaborate on using hybrid quantum technology for business optimization challenges. Collateral optimization is one example of the challenges the teams may explore. Critical Quote: “Working with HSBC allows […]
Quantum technology’s future rests on the exploitation of fascinating quantum mechanics concepts—such as high-dimensional quantum states. Think of these states as basic ingredients of quantum information science and quantum tech. To manipulate these states, scientists […]
Insider Brief PacketLight and ID Quantique (IDQ) announced joint solutions that will offer quantum-safe security. Combining IDQ’s QKD with PacketLight network encryption equipment enables the retrofit and upgrade of existing fiber optics. The teams say […]
Quantum 7, 1104 (2023). https://doi.org/10.22331/q-2023-09-07-1104 A powerful operational paradigm for distributed quantum information processing involves manipulating pre-shared entanglement by local operations and classical communication (LOCC). The LOCC round complexity of a given task describes how […]
The sun looks immutable, a boring celestial lightbulb that’s always turned on. But this fusion-powered ball of plasma is in constant flux. Every 11 years or so, it swings between slumber and an active, unruly […]
Quantum 7, 1103 (2023). https://doi.org/10.22331/q-2023-09-07-1103 We show that the proof of the generalised quantum Stein’s lemma [Brandão & Plenio, Commun. Math. Phys. 295, 791 (2010)] is not correct due to a gap in the argument […]
Quantum 7, 1102 (2023). https://doi.org/10.22331/q-2023-09-07-1102 Integral representations of quantum relative entropy, and of the directional second and higher order derivatives of von Neumann entropy, are established, and used to give simple proofs of fundamental, known […]
