Scientists at the University of Exeter and the University of Sheffield have made a pivotal new breakthrough in the quest to control light to evolve the next generation of quantum sensing and computing. They have […]
Researchers at QuTech have demonstrated a key technology for linking quantum nodes over existing telecom fiber, by realizing quantum interference of photons emitted by quantum devices at telecom wavelengths. The technique also allows for compensating […]
A new review investigates the search of Majorana fermions in iron-based superconductors. The elusive Majorana fermion, or ‘angel particle‘ simultaneously behaves like a particle and an antiparticle — and surprisingly remains stable rather than being […]
Researchers at Paderborn University have developed a new technology for manipulating light that can be used as a basis for future optical quantum computers. New optical elements for manipulating light will allow for more advanced […]
Researchers at MIT developed a method to enable quantum sensors to detect any arbitrary frequency, with no loss of their ability to measure nanometer-scale features. Quantum sensors detect the most minute variations in magnetic or […]
Scientists at EPFL, Switzerland, have built a compact waveguide amplifier by successfully incorporating rare-earth ions into integrated photonic circuits. The device produces record output power compared to commercial fiber amplifiers, a first in the development […]
Researchers at University of Tsukuba measured tiny magnetic fields with unprecedented speed. By monitoring spins at Nitrogen-Vacancy (NV) centers along using ultrafast spectroscopy. They hence demonstrated how ultrafast spectroscopy can be used to improve the […]
A team of researchers has proposed a deterministic hybrid protection scheme utilizing strong but feasible interactions with two-level ancillas immune to spontaneous emission. They have verified the robustness of the scheme against the dephasing of qubit ancilla.
P-computers are powered by probabilistic bits (p-bits), which interact with other p-bits in the same system. Unlike the bits in classical computers, which are in a 0 or a 1 state, or qubits, which can […]
A team of physicists at University of Colorado and NIST demonstrated that it could read out the signals from a type of qubit called a superconducting qubit using laser light, and without destroying the qubit […]
