In a new breakthrough, researchers at the University of Copenhagen, in collaboration with Ruhr University Bochum, have solved a problem that has caused quantum researchers headaches for years. The researchers can now control two quantum […]
Peter Chapman, CEO of IonQ, is interviewed by Yuval Boger. Peter and Yuval discuss IonQ’s plans to scale their computers and deliver business value, the best application-development partners for quantum customers, IonQ’s new quantum manufacturing […]
Starting with the emergence of quantum mechanics, the world of physics has been divided between classical and quantum physics. Classical physics deals with the motions of objects we typically see every day in the macroscopic […]
Quasiparticles — long-lived particle-like excitations — are a cornerstone of quantum physics, with famous examples such as Cooper pairs in superconductivity and, recently, Dirac quasiparticles in graphene. Now, researchers have discovered quasiparticles in a classical […]
Quantum 7, 909 (2023). https://doi.org/10.22331/q-2023-01-26-909 We introduce a variational quantum algorithm to solve unconstrained black box binary optimization problems, i.e., problems in which the objective function is given as black box. This is in contrast […]
Quantum 7, 908 (2023). https://doi.org/10.22331/q-2023-01-26-908 This work studies pulse based variational quantum algorithms (VQAs), which are designed to determine the ground state of a quantum mechanical system by combining classical and quantum hardware. In contrast […]
People often think they know what causes chronic depression. Surveys indicate that more than 80% of the public blames a “chemical imbalance” in the brain. That idea is widespread in pop psychology and cited in […]
Researchers have developed a new detector that can precisely measure single photons at very high rates. The new device could help make high-speed quantum communication practical. Click to rate this post! [Total: 0 Average: 0]You […]
In recent years, many physicists and computer scientists have been working on the development of quantum computing technologies. These technologies are based on qubits, the basic units of quantum information. Click to rate this post! […]
The standard model of particle physics tells us that most particles we observe are made up of combinations of just six types of fundamental entities called quarks. However, there are still many mysteries, one of […]
