Switching with a few photons for quantum computing
(Phys.org)—Quantum computing, where bits of information, or "qubits," are represented by the state of single atomic particles or photons of light, won't be of much use unless we can read the results. Cornell ...
Neutrons confirm their potential to probe nanomagnets and the future of quantum computing
(Phys.org)—Neutron scientists at the ILL have partnered with researchers from the University of Manchester, the University of Parma, the Rutherford Laboratory and the University of Bern to investigate molecular ...
Bismuth provides perfect dance partners for quantum computing qubits
New research has demonstrated a way to make bismuth electrons and nuclei work together as qubits in a quantum computer.
The beginning of everything: A new paradigm shift for the infant universe
(Phys.org)—A new paradigm for understanding the earliest eras in the history of the universe has been developed by scientists at Penn State University. Using techniques from an area of modern physics called ...
First noiseless single photon amplifier
Research physicists have demonstrated the first device capable of amplifying the information in a single particle of light without adding noise.
Quantum kisses change the color of nothing
Even empty gaps have a colour. Now scientists have shown that quantum jumps of electrons can change the colour of gaps between nano-sized balls of gold. The new results, published today in the journal Nature, set a ...
Quantum communication without entanglement could perform faster than previously thought possible
Researchers look beyond space and time to cope with quantum theory
Physicists have proposed an experiment that could force us to make a choice between extremes to describe the behaviour of the Universe.
Quantum computing with recycled particles
A research team from the University of Bristol's Centre for Quantum Photonics (CQP) have brought the reality of a quantum computer one step closer by experimentally demonstrating a technique for significantly reducing the ...
Atomic nuclei intimately entangled by a quantum measurement
Scientists from the Netherlands (Delft University of Technology and the FOM Foundation) and the UK (Element Six) have brought two atomic nuclei in a diamond into a quantum entangled state. This exotic relation ...
Researchers devise a means to 'gently' measure qubit without destroying superposition
Physicists experimentally demonstrate one-way quantum steering
Point-like defects in a quantum fluid behave like magnetic monopoles
The world's most stable laser also promises heightened test precision
(Phys.org)—The world's most stable laser – with frequency variation of no more than 2 parts in 10,000 trillion – has been developed and tested by an international collaboration of scientists at NIST/JILA ...
