Now you see it: Real-space observation of many-body proton tunneling in water nanocluster
There's more to quantum tunneling than meets the eye – or rather, the visualization technique. (Quantum tunneling is a quantum mechanical phenomenon where a particle transitions through a classically-forbidden energy state.) ...
New research signals big future for quantum radar
A prototype quantum radar that has the potential to detect objects which are invisible to conventional systems has been developed by an international research team led by a quantum information scientist at the University ...

Physicists show that it is impossible to mask quantum information in correlations
Information is typically stored in physical systems, such as memory devices. But in a new study, physicists have investigated an alternative way to store and hide information, which is by storing it only in the quantum correlations ...
Physicists find direct evidence of strong electron correlation in a 2D material for the first time
In recent years, physicists have discovered materials that are able to switch their electrical character from a metal to an insulator, and even to a superconductor, which is a material in a friction-free state that allows ...

Quantum correlations make you never fail a test again
(Phys.org) —In the burgeoning field of quantum metrology, quantum effects are exploited to improve the precision when measuring a variety of parameters, such as phase, frequency, and magnetic fields. A main goal of this ...
Quantum 1, classical 0: Bell nonlocality universally confirmed in any large communication complexity advantage
(Phys.org)—The relationship between communication complexity problems, Bell nonlocal correlations and the advantage of quantum over classical strategies has long been recognized, but has been confirmed in only two problems. ...
Quantum guessing game reveals insight into stronger-than-quantum correlations
(PhysOrg.com) -- In information processing, physicists are often in search of ways to turn classical strategies into quantum ones, with the implication that the quantum version is somehow stronger, faster, or more secure ...
Strings attached to future high temperature superconductivity
The behaviour of strongly correlated electron systems, such as high temperature superconductors, defies explanation in the language of ordinary quantum theory. A seemingly unrelated area of physics, string theory, might give ...

All quantum communication involves nonlocality
Researchers of CWI, University of Gdansk, Gdansk University of Technology, Adam Mickiewicz University and the University of Cambridge have proven that quantum communication is based on nonlocality. They show that whenever ...
