The measurement postulate is crucial to quantum mechanics. If we measure a quantum system, we can only get one of the eigenvalues of the measured observable, such as position, energy and so on, with a […]

What happens when very short pulses of laser light strike a magnetic material? A large international collaboration led by the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory set out to answer this very question. […]
Researchers at Okinawa Institute of Science and Technology Graduate University in Japan have recently been investigating situations in which two distinct Hamiltonians could be used to simulate the same physical phenomena. A Hamiltonian is a […]
The world is one step closer to ultimately secure conference calls, thanks to a collaboration between Quantum Communications Hub researchers and their German colleagues, enabling a quantum-secure conversation to take place between four parties simultaneously. […]
Left- or right-handedness is a symmetry property that many macroscopic objects also exhibit and which is of immense importance, particularly for the bioactivity of organic molecules. Chirality is also relevant for physical or chemical properties […]
Quantum computers, with their promises of creating new materials and solving intractable mathematical problems, are a dream of many physicists. Now, they are slowly approaching viable realization in many laboratories all over the world. But […]
Majorana particles have been getting bad publicity: a claimed discovery in ultracold nanowires had to be retracted. Now Leiden physicists open up a new door to detecting Majoranas in a different experimental system, the Fu-Kane […]
During the ’90s, engineers made major advances in the telecom arena spreading out the network to distances beyond the cities and metropolitan areas. To achieve this scalability factor, they used repeaters, which enhanced attenuated signals […]
For some 30 years, scientists have used superconducting materials to record the tiniest specks of light imaginable—individual photons, or single particles of light. However, these detectors, which consist of ultracold wires only about one-thousandth the […]
Quantum computing and quantum sensing have the potential to be vastly more powerful than their classical counterparts. Not only could a fully realized quantum computer take just seconds to solve equations that would take a […]
