‘Quantum microphone’ detects sound at the atomic level

‘Quantum microphone’ detects sound at the atomic level Researchers at Stanford have developed a "quantum microphone" which can detect the smallest known units of sound -- packets of vibrational energy called phonons. The device could form the basis for even more efficient quantum computers. Phonons have previously been impossible to measure because traditional microphones are not nearly sensitive enough to pick them up. A microphone works by detecting when a sound wave interacts with a membrane, but the phonons are so small that they can't be detected individually due to the Heisenberg Uncertainty Principle.

IBM continues to push its quantum computing efforts forward and today announced that it will soon make a 53 - qubit quantum computer available to clients of its IBM Q Network. The new system, which is scheduled to go online in the middle of next month, will be the largest universal quantum computer

IBM's 14th quantum computer is its most powerful so far, a model with 53 of the qubits that form the fundamental data-processing element at the heart of the system. The system, available online to quantum computing customers in October, is a big step up from the last IBM Q machine with 20 qubits and should help advance the marriage of classical computers with the crazy realm of quantum physics.

Quantum computing remains a highly experimental field, limited by the difficult physics of the ultra-small and by the need to keep the machines refrigerated to within a hair's breadth of absolute zero to keep outside disturbances from ruining any calculations.

Physicists Have Finally Built a Quantum X-Ray Device

Physicists Have Finally Built a Quantum X-Ray Device A team of researchers has just demonstrated quantum enhancement in an actual X-ray machine, achieving the desirable goal of eliminating background noise for precision detection. The relationships between photon pairs on quantum scales can be exploited to create sharper, higher-resolution images than classical optics. This emerging field is called quantum imaging, and it has some really impressive potential - particularly since, using optical light, it can be used to show objects that can't usually be seen, like bones and organs. Quantum correlation describes a number of different relationships between photon pairs.

Scientists Hanhee Paik and Martin Sandberg from IBM ’ s quantum computing research team provide an overview of the architecture of IBM ’ s new 16- qubit quantum processor, its potential uses and how it compares to the previous generation 5- qubit processor.

IBM has unveiled its latest quantum device: the Q System One, a beautifully polished 20- qubit machine . However, it’s still an experimental device, and not ready to delivery on the biggest Share All sharing options for: IBM ’ s new quantum computer is a symbol, not a breakthrough.

But if engineers and scientists can continue the progress, quantum computers could help solve computing problems that are, in practice, impossible on today's classical computers. That includes things like simulating the complexities of real-world molecules used in medical drugs and materials science, optimizing financial investment performance, and delivering packages with a minimum of time and fuel.

Quantum computers rely on qubits to store and process data. Unlike regular computer bits, which can store either a zero or a one, qubits can store a combination of both through a concept called superposition. Another factor is entanglement, which links the states of two qubits even if they're separated.

Physicists To Split $4 Million Breakthrough Prize For Supergravity

Physicists To Split $4 Million Breakthrough Prize For Supergravity Physicists Sergio Ferrara, Dan Freedman, and Peter van Nieuwenhuizen will split a $US3 ($4) million Breakthrough Prize for their theory of supergravity, which drives much of today’s physics research toward our understanding of the universe. The Breakthrough Prize is an annual award to recognise groundbreaking science, funded by Russian-Israeli billionaire Yuri Milner. Though Breakthrough Prizes are awarded annually, “special” Breakthrough Prizes can be awarded any time and need not honour recent work. In fact, the researchers behind today’s award thought they’d missed the chance to win it.

Quantum computing has bits, just like any computer . But instead of ones and zeros, its quantum bits, or However, the superposition that occurs in a quantum computer is very different than any IBM ’ s team’s latest engineering advances include combining five superconducting qubits in a latticed

IBM ' s new 53 - qubit quantum computer will be available in the newly opened Quantum Computation Center in Armonk, NY on Wednesday, as part of an initiative to make quantum computers more accessible for enterprises, startups, and academic researchers.

"The new quantum system is important because it offers a larger lattice and gives users the ability to run even more complex entanglement and connectivity experiments," said Dario Gil, director of IBM Research.

IBM is competing with companies like Google, Microsoft , Honeywell, Rigetti Computing, IonQ, Intel and NTT in the race to make useful quantum computers. Another company, D-Wave, uses a different approach called annealing that's already got some customers, while AT&T and others are pursuing the even more distant realm of quantum networking.

If you're used to classical computers, you'll be familiar with powers of 2 that crop up all over the place: 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, etc. So what's up with a quantum computer with 53 qubits? It stems from the hexagonally derived lattice of qubits that's advantageous when it comes to minimizing unwanted interactions, IBM said.

IBM is pushing a concept called quantum volume to measure quantum computer performance. It's designed to capture more aspects of quantum computing than just qubits, which can be misleading since other factors can degrade qubit performance. IBM's 20-qubit quantum computers, of which there are now five, have a quantum volume of 16, but IBM hasn't yet tested the 53-qubit model.

British Airways computer problem strands 20,000.
LONDON (AP) — British Airways canceled more than 100 flights to and from London airports and delayed many others Wednesday after its check-in systems were hit by computer problems, stranding about 20,000 passengers. The airline said Wednesday afternoon that it had resolved a "temporary systems issue" that caused delays and cancellations for short-haul flights from Heathrow, Gatwick and London City airports for much of the day. BA canceled 117
