Quantum memory for communication networks of the future

Researchers from the Niels Bohr Institute at the University of Copenhagen have succeeded in storing quantum information using two 'entangled' light beams. Quantum memory or information storage is a necessary element of future ...

Three tiny qubits, another big step toward quantum computing

(PhysOrg.com) -- The rules that govern the world of the very small, quantum mechanics, are known for being bizarre. One of the strangest tenets is something called quantum entanglement, in which two or more objects (such ...

Physicists set guidelines for qubit candidates

(PhysOrg.com) -- To build a quantum computer, it's essential to be able to quickly and efficiently manipulate the quantum states of qubits. The qubits, which are the basic unit of quantum information, can be composed of many ...

Straightening messy correlations with a quantum comb

Quantum computing promises ultra-fast communication, computation and more powerful ways to encrypt sensitive information. But trying to use quantum states as carriers of information is an extremely delicate business. Now ...

Creating a six-qubit cluster state

(PhysOrg.com) -- Many scientists believe that quantum entanglement is required in order for effective quantum computing. Entanglement takes place when there is a connection that exists between two objects - even when they ...

Physicists Investigate Unusual Four-Qubit Entanglement

(PhysOrg.com) -- For the first time, physicists have experimentally demonstrated a four-qubit bound-entangled state - a peculiar form of entanglement that cannot be distilled (optimized) by the usual means. However, the scientists ...

Computing in the quantum dimension

A huge consortium of European researchers is solving some of the fundamental obstacles blocking real quantum computing applications in the short term. At the same time, it is helping to pave the way to a quantum computer.
