An alternative way to manipulate quantum states

Researchers at ETH Zurich have shown that quantum states of single electron spins can be controlled by currents of electrons whose spins are evenly aligned. In the future, this method could be used in electronic circuit elements.

Physicists find a new way to represent π

While investigating how string theory can be used to explain certain physical phenomena, scientists at the Indian Institute of Science (IISc) have stumbled upon on a new series representation for the irrational number π. ...

Ultra-high spectral purity revealed in exciton-polariton laser

Exciton-polariton lasers, renowned for their low-power operation, have long tantalized researchers with their promise for practical low-energy applications. However, until now, a clean measurement of the laser's linewidth, ...

Quantum computing trade-off problem addressed by new system

The potential of quantum computers is currently thwarted by a trade-off problem. Quantum systems that can carry out complex operations are less tolerant to errors and noise, while systems that are more protected against noise ...

Squeezing Schrödinger's cat may increase quantum sensitivity

One of the most counter-intuitive aspects of quantum physics is the idea that a quantum system, unlike a physical system governed by the everyday physics of the macroscopic universe, can exist in two states at once even if ...
