Technique will Lead to Better Optical Probes for Studying Electron Dynamics

Scientists at RIKEN have developed a way to measure the wavelike properties of ultrafast (attosecond) light pulses - an important step toward being able to probe the dynamics of electrons, atoms and molecules.

Paving the Way for Quantum Experiments on a Macroscopic Scale

An astrophysics experiment in America has demonstrated how fundamental research in one subject area can have a profound effect on work in another as the instruments used for the Laser Interferometer Gravitational-Wave Observatory (LIGO) pave the way for quantum experiments on a macroscopic scale.

Quantum Computers And Tossing A Coin In The Microcosm

Professor Dieter Meschede's group has been working on the development of so-called quantum computers now for many years. With the 'quantum walk' the team has now achieved a further seminal step on this path. 'With the effect we have demonstrated, entirely new algorithms can be implemented,' Artur Widera explains.

Miniaturized Lasers Emit Quantum Light

For more than 100 years it has been known that light comes in small packages, the so-called photons. The discovery of this quantization of the light field has opened up a new field of physics - quantum optics.

Viable Way to Manipulate a Single "Bit" in a Quantum Processor

Physicists at the National Institute of Standards and Technology (NIST) have overcome a hurdle in quantum computer development, having devised* a viable way to manipulate a single "bit" in a quantum processor without disturbing the information stored in its neighbors.

Quantum Bit Memory Lengthen by 1,000 times using Lasers

The scientists, including the University of Michigan's Duncan Steel, used lasers to elicit a previously undiscovered natural feedback reaction that stabilizes the quantum dot's magnetic field, lengthening the stable existence of the quantum bit by several orders of magnitude, or more than 1,000 times.
