Quantum

A new micro-ring resonator has been developed that is claimed to produce copious numbers of entangled photons using miniscule amounts of energy and can fit onto an ordinary silicon chip. This advance promises to bring quantum computing, communication, and cryptography closer to a practical reality.

As can be expected from TV manufacturers across the board, LG has announced that it will unveil a new 4K UHD TV at CES 2015. What makes this (as yet nameless) model interesting is the fact that it will make use of quantum dot technology. In short, that means brighter, more colorful viewing.

Quantum technologies are becoming increasingly difficult to advance without memories able to appropriately store atomic-spin information. To help address this problem, scientists from the University of Warsaw claim to have developed a laser-driven atomic memory.

Physicists at the University of Geneva claim to have succeeded in passing information from light into matter using the teleportation of a photon via optical fiber cable to a receiving crystal located over 25 km (15 m) away

Scientists at Princeton University have developed a quantum system that locks individual photons together in such a way that they behave like a solid or liquid. The research impacts on our understandings of quantum mechanics, and it may lead to the creation of room-temperature superconductors.

A new device is set to make unbreakable, quantum-based cryptographic security available for everyone for the very first time. To do this, the device incorporates the quantum mechanics of random photon polarization to generate random numbers and create cryptographic keys.

Using high-powered laser interferometers to determine if space-time is a quantum system made up of countless tiny bits of information, Fermilab scientists are conducting an experiment to see if the universe is "real" or a holographic 3-D illusion.

Researchers at the University of Queensland, Australia claim to have simulated the behavior of a single photon traveling back in time and interacting with an older version of itself, in an effort to investigate how such a particle would behave.

Scientists have recently experimented with a combination of biological and photonic quantum mechanical states to form a new half-light half-matter particle called the “polariton.” It could help realize fully synthetic systems that replicate biological photosynthesis.

Researchers at MIT have used a new method to craft solar cells from ultra-thin layers of quantum dots to set a new record of nine percent for the most efficient quantum-dot solar cells produced to date.

Google has just launched its "Quantum Computing Playground," which is a new web-based integrated development environment (IDE) interface that allows users to write, run and debug software that makes use of quantum algorithms.

Physicists working at the Blackett Physics Laboratory in Imperial College London have designed an experiment to validate one of the most tantalizing hypotheses in quantum electrodynamics: the theory that matter could be created using nothing more than pure light.
