Scattering takes place across the universe at large and miniscule scales. Billiard balls clank off each other in bars, the nuclei of atoms collide to power the stars and create heavy elements, and even sound […]
Data security on the internet is under threat: in the future, quantum computers could decode even encrypted files sent over the internet in no time. Researchers worldwide are, therefore, experimenting with quantum networks that will […]
Qubits — the fundamental units of quantum information — drive entire tech sectors. Among them, superconducting qubits could be instrumental in building a large-scale quantum computer, but they rely on electrical signals and are difficult […]
Researchers have discovered that superconducting nanowire photon detectors can also be used as highly accurate particle detectors, and they have found the optimal nanowire size for high detection efficiency. Click to rate this post! [Total: […]
Insider Brief Quantinuum and RIKEN have successfully installed Quantinuum’s “Reimei” quantum computer at RIKEN’s Wako campus in Japan, marking the first on-premise deployment of Quantinuum’s quantum technology outside the U.S. The trapped-ion quantum computer will […]
Q-CTRL has expanded its U.S. presence with a new office in San Francisco to better access top talent, industry partnerships, and venture capital in Silicon Valley. The company aims to leverage the region’s deep technology […]
Quantum 9, 1631 (2025). https://doi.org/10.22331/q-2025-02-11-1631 Strongly-correlated quantum many-body systems are difficult to study and simulate classically. We recently proposed a variational quantum eigensolver (VQE) based on the multiscale entanglement renormalization ansatz (MERA) with tensors constrained […]
Quantum 9, 1630 (2025). https://doi.org/10.22331/q-2025-02-11-1630 Accurate simulations of vibrational molecular spectra are expensive on conventional computers. Compared to the electronic structure problem, the vibrational structure problem with quantum computers is less investigated. In this work […]
Quantum 9, 1629 (2025). https://doi.org/10.22331/q-2025-02-11-1629 Recent results in relativistic quantum information and quantum thermodynamics have independently shown that in the quantum regime, a system may fail to thermalise when subject to quantum-controlled application of the […]
Quantum 9, 1628 (2025). https://doi.org/10.22331/q-2025-02-11-1628 What does it mean for a causal structure to be `unknown’? Can we even talk about `repetitions’ of an experiment without prior knowledge of causal relations? And under what conditions […]
