Scientists calculate absolute quantum speed limit for electronics

It often feels like electronics will continue to get faster forever, but at some point the laws of physics will intervene to put a stop to that. Now scientists have calculated the ultimate speed limit – the point at which quantum mechanics prevents mic… Continue reading Scientists calculate absolute quantum speed limit for electronics

Record-setting hybrid atom array could power quantum computer RAM and CPU

Researchers at the University of Chicago have demonstrated a key technology that could help scale up quantum computers, and used it to create a model with a record-breaking 512 qubits. The team combined atoms of two elements into an array, so that one … Continue reading Record-setting hybrid atom array could power quantum computer RAM and CPU

Physicists measure gravitational time warp to within one millimeter

The flow of time isn’t as consistent as we might think – gravity slows it down, so clocks on the surface of Earth tick slower than those in space. Now researchers have measured time passing at different speeds across just one millimeter, the smallest d… Continue reading Physicists measure gravitational time warp to within one millimeter

Quasiparticles used to generate millions of truly random numbers a second

Random numbers are crucial for computing, but our current algorithms aren’t truly random. Researchers at Brown University have now found a way to tap into the fluctuations of quasiparticles to generate millions of truly random numbers per second.Contin… Continue reading Quasiparticles used to generate millions of truly random numbers a second

Silicon quantum computing surpasses 99% accuracy in three studies

Three teams of scientists from around the world have achieved a major milestone in quantum computing. All three groups demonstrated better than 99 percent accuracy in silicon-based quantum devices, paving the way for practical, scalable quantum compute… Continue reading Silicon quantum computing surpasses 99% accuracy in three studies

Proof of concept verifies physics that could enable quantum batteries

Quantum batteries could one day revolutionize energy storage through what seems like a paradox – the bigger the battery, the faster it charges. For the first time, a team of scientists has now demonstrated the quantum mechanical principle of superabsor… Continue reading Proof of concept verifies physics that could enable quantum batteries

“Quantum tornadoes” mark crossover from classical to quantum physics

The universe is governed by two sets of seemingly incompatible laws of physics – there’s the classical physics we’re used to on our scale, and the spooky world of quantum physics on the atomic scale. MIT physicists have now observed the moment atoms sw… Continue reading “Quantum tornadoes” mark crossover from classical to quantum physics

Harvard scientists observe new state of matter, a quantum spin liquid

An exotic state of matter originally hypothesized almost 50 years ago has been observed for the first time. Created by Harvard researchers, this material called quantum spin liquid could eventually help improve quantum computers.Continue ReadingCategor… Continue reading Harvard scientists observe new state of matter, a quantum spin liquid

Simplified quantum computer can be made with off-the-shelf components

Quantum computers could one day blow boring old classical computers out of the water, but so far their complexity limits their usefulness. Engineers at Stanford have now demonstrated a new relatively simple design for a quantum computer where a single … Continue reading Simplified quantum computer can be made with off-the-shelf components
