One small step for electrons, one giant leap for quantum computers

One small step for electrons, one giant leap for quantum computers

September 25, 2019

Quantum computing has revolutionary potential, but transferring information within a quantum system remains a challenge. By transferring the state of electrons, Rochester research brings scientists one step closer to creating fully functional quantum computers.

Resolving quantum ‘weirdness’: A new look at the duality of light

Resolving quantum ‘weirdness’: A new look at the duality of light

September 6, 2018

For 90 years physicists have known that incompatibly opposite properties are inherent in all elementary particles. Now Rochester researchers say they’ve resolved this weird and inescapable wave-particle duality.

Chemists go ‘back to the future’ to untangle quantum dot mystery

Chemists go ‘back to the future’ to untangle quantum dot mystery

December 12, 2017

For more than 30 years, researchers have been creating quantum dots – nanoscale semiconductors with remarkable properties. But quantum dot synthesis has occurred largely by trial and error. Thanks to the work of two Rochester chemists, that may be about to change.

Quantum magic makes quick work of measuring frequency

Quantum magic makes quick work of measuring frequency

November 8, 2017

Using the strange rules of quantum mechanics, researchers were able to put a quantum bit in a superposition of two different energy states at the same time in order to speed up the accurate measurement of frequencies.

Enigma Machine takes a quantum leap

Enigma Machine takes a quantum leap

September 6, 2016

Researchers have developed a “quantum enigma machine” to improve on data encryption. The device manipulates photons to create an unbreakable encrypted message with a key that’s far shorter than the message—the first time that has ever been done.

How real is reality?

How real is reality?

January 5, 2016

Reality, in other words, seems pretty stubborn, pretty fixed — and pretty much independent of whatever is going on in your head. But is it? Is it really all those things?

There’s a hidden connection between pi and quantum mechanics

There’s a hidden connection between pi and quantum mechanics

November 16, 2015

Physicists have uncovered a hidden connection between a famous 350-year-old mathematical formula for pi, everyone’s favourite irrational number, and quantum mechanics. At least one mathematician has pronounced the discovery “a cunning piece of magic.”
