Bringing a power tool from math into quantum computing

The Fourier transform is an important mathematical tool that decomposes a function or dataset into a its constituent frequencies, much like one could decompose a musical chord into a combination of its notes. It is used across ...

Anti-resonant hollow-core optical fiber reduces 'noise'

A new hollow optical fiber greatly reduces the "noise" interfering with the signals it transmits compared to the single-mode fibers now widely used, researchers at the University of Rochester report.

Quantum machines learn 'quantum data'

Skoltech scientists have shown that quantum enhanced machine learning can be used on quantum (as opposed to classical) data, overcoming a significant slowdown common to these applications and opening a "fertile ground to ...

Solving materials problems with a quantum computer

Quantum computers have enormous potential for calculations using novel algorithms and involving amounts of data far beyond the capacity of today's supercomputers. While such computers have been built, they are still in their ...

Cooling magnets with sound

Today, most quantum experiments are carried out with the help of light, including those in nanomechanics, in which tiny objects are cooled with electromagnetic waves to such an extent that they reveal quantum properties. ...

Bending diamond is possible, at the nanoscale

Diamond is prized by scientists and jewelers alike, largely for a range of extraordinary properties including exceptional hardness. Now a team of Australian scientists has discovered diamond can be bent and deformed, at the ...

Topological nanoelectronics

Topological insulators are materials with astonishing properties: Electric current flows only along their surfaces or edges, whereas the interior of the material behaves as an insulator. In 2007, Professor Laurens Molenkamp ...

Quantum information science

Quantum information science concerns information science that depends on quantum effects in physics. It includes theoretical issues in computational models as well as more experimental topics in quantum physics including what can and cannot be done with quantum information. The term quantum information theory is sometimes used, but it fails to encompass experimental research in the area.

Subfields include:

Quantum teleportation is one well-known quantum information processing operation which reliably transfers an unknown quantum state from one point to another distant point, destroying the original state in the process.
