Animation Quantum teleportation is an important step in improving quantum computing. “Beam me up” is one of the most famous catchphrases from the Star Trek series. It is the command issued when a character wishes to teleport from a remote location back to the Starship Enterprise. While human teleportation exists only […]

PNNL quantum algorithm theorist and developer Nathan Wiebe is applying ideas from data science and gaming hacks to quantum computing. Everyone working on quantum computers knows the devices are error prone. The basic unit of quantum programming – the quantum gate – fails about once every hundred operations. And that error […]

Credit: CC0 Public Domain Army researchers predict quantum computer circuits that will no longer need extremely cold temperatures to function could become a reality after about a decade. For years, solid-state quantum technology that operates at room temperature seemed remote. While the application of transparent crystals with optical nonlinearities had emerged as […]

Constructing a small-scale circuit to further examine and explore the possibility. Credit: Tokyo University of Science The basic units of a quantum computer can be rearranged in 2D to solve typical design and operation challenges. Quantum computing is increasingly becoming the focus of scientists in fields such as physics and […]

A new “refrigerator” super-cools molecules to nanokelvin temperatures. The technique may enable more complex, molecule-based quantum computing. Credit: José-Luis Olivares, MIT Technique may enable molecule-based quantum computing. For years, scientists have looked for ways to cool molecules down to ultracold temperatures, at which point the molecules should slow to a […]

MIT researchers have observed mysterious Majorana fermions in islands of gold. The discovery could lead to new family of robust qubits for quantum computing. Physicists’ discovery could lead to a new family of robust qubits for quantum computing. Physicists at MIT and elsewhere have observed evidence of Majorana fermions — particles that are […]

Quantum computers that are exponentially faster than any of our current classical computers and are capable of code-breaking applications could be available in 12 to 15 years, posing major risks to the security of current communications systems, according to a new RAND Corporation report. The security risks posed by this […]

Scientists from Skolkovo Institute of Science and Technology (Skoltech), a private graduate research institute in Moscow, Russia, discovered and quantified what appears to be a fundamental limitation in the wildly adopted quantum approach initiated by Google. Google is racing to develop quantum-enhanced processors that utilize quantum mechanical effects to one […]

Electromagnetically induced transparency (EIT) is ‘tuned’ by two particles on the optical resonator. The different locations of particles control the propagation of light in either clockwise or counterclockwise directions, which switch on (upper configuration) or off (lower configuration) the interference of light, leading to controllable brightness (EIT) and darkness in […]
