1.5×1.5mm quantum cascade laser has a surface emission of 5W

Improving on previously published room-temperature large-area photonic crystals (PhCs) Quantum cascade lasers (QCLs), researchers from ETH Zurich have fabricated a device with 5W surface-emitting peak power when driven in pulsed operation. by Julien Happich @ eenewseurope.com Their...

Three quantum computer components integrated on one chip

Scientists at the University of Stuttgart and the KIT succeed in important further development on the way to quantum computers. Quantum computers one day should be able to solve certain computing problems much faster than a classical computer. One of the most promising approaches is...

The First 3D Quantum Liquid Crystals

Strong electron interactions can drive metallic systems toward a variety of well-known symmetry-broken phases, but the instabilities of correlated metals with strong spin-orbit coupling have only recently begun to be explored. A team of physicists at the Institute for Quantum...

On-Chip Microwave Laser

Lasers are everywhere these days: at the checkout in the supermarket, in the CD player in the lounge – and quantum researchers need them to test qubits in the (future) quantum computers. For most applications, today's large, inefficient lasers are a perfectly adequate solution, but...

Electrons Counter-Intuitive Movement

Our 'common sense' would say that when an object moves from point A to point B it necessarily has to also move through all the points between A and B. This is, however, not true for electrons in the quantum world, where these intuitive truths are not valid. Electrons can, for...
