IQC to Build Compact Prototype Quantum Key Distribution Receiver for Low-Cost Microsatellite Mission

Institute for Quantum Computing (IQC) researcher Dr. Thomas Jennewein and Dr. Vadim Makarov have received a $600,000 contract from the Canadian Space Agency (CSA) to design and build a compact prototype quantum key distribution receiver (QKDR) suitable for a low-cost microsatellite mission.

Researchers Exploit Decay to Create Entanglement of Atomic Systems

Usually, when researchers work with quantum information, they do everything they can to prevent the information from decaying. Now researchers at the Niels Bohr Institute, among others, have flipped things around and are exploiting the decay to create the so-called entanglement of atomic systems, which is the foundation for quantum information processing. The results are published in the scientific journal, Nature.

NIST Experiment Shows How Quantum Computing Can Benefit from Lost Data

Suggesting that quantum computers might benefit from losing some data, physicists at the National Institute of Standards and Technology (NIST) have entangled—linked the quantum properties of—two ions by leaking judiciously chosen information to the environment.

Physicists Successfully Generate Single Color Quantum Light Particles for Quantum Information Applications

Physicists at the University of Basel have been successful in generating photons - the quantum particles of light – with only one color. This is useful for quantum information. The scientists have actively stabilized the wavelength of the photons emitted by a semiconductor thereby neutralizing the charge noise in the semiconductor.
