A quarter century ago, theoretical physicists at the University of Innsbruck made the first proposal on how to transmit quantum information via quantum repeaters over long distances, which would open the door to the construction […]
Quantum 7, 1018 (2023). https://doi.org/10.22331/q-2023-05-23-1018 We present an algorithm that uses block encoding on a quantum computer to exactly construct a Krylov space, which can be used as the basis for the Lanczos method to […]
Insider Brief SandboxAQ’s reported a successful tested of its advanced, quantum sensor-based magnetic anomaly navigation system. The test flights were conducted last week at Travis Air Force Base by the 60th Air Mobility Wing. The […]
Quantum 7, 1017 (2023). https://doi.org/10.22331/q-2023-05-23-1017 Bosonic Gaussian states are a special class of quantum states in an infinite dimensional Hilbert space that are relevant to universal continuous-variable quantum computation as well as to near-term quantum […]
Have you ever admired how the slats of a hardwood floor fit together so cleanly, or how the hexagons underneath your bathroom rug perfectly meet up? These are examples of geometric tilings, arrangements of shapes […]
Quantum 7, 1016 (2023). https://doi.org/10.22331/q-2023-05-23-1016 We study the phenomena of topological amplification in arrays of parametric oscillators. We find two phases of topological amplification, both with directional transport and exponential gain with the number of […]
Quantum 7, 1015 (2023). https://doi.org/10.22331/q-2023-05-23-1015 Relational Quantum Mechanics (RQM) claims to be an interpretation of quantum theory [20]. However, there are significant departures from quantum theory: (i) in RQM measurement outcomes arise from interactions which […]
Quantum 7, 1014 (2023). https://doi.org/10.22331/q-2023-05-23-1014 Physical unclonable functions(PUFs) provide a unique fingerprint to a physical entity by exploiting the inherent physical randomness. Gao et al. discussed the vulnerability of most current-day PUFs to sophisticated machine […]
Insider Brief IBM roadmap calls for a 100,000-qubit quantum-centric supercomputer by 2023. The company is setting up critical research partnerships with world-leading universities and scientific institutions. Image: IBM Quantum System Two, visually rendered here, is […]
Insider Brief NVIDIA, Rolls-Royce and Classiq worked together to use quantum computers to build more efficient jet engines. Using NVIDIA’s quantum computing platform, the companies have designed and simulated the world’s largest quantum computing circuit […]
