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 […]
Quantum 7, 907 (2023). https://doi.org/10.22331/q-2023-01-26-907 We investigate nonlocal quantum correlations arising between multiple two-level impurity atoms coupled to an ultracold bosonic gas. We find that the environment-induced dynamics of the impurity subsystem can generate nonlocal […]
Quantum 7, 906 (2023). https://doi.org/10.22331/q-2023-01-26-906 The accurate estimation of quantum observables is a critical task in science. With progress on the hardware, measuring a quantum system will become increasingly demanding, particularly for variational protocols that […]
