### Quantum computers could greatly accelerate machine learning

(Phys.org)—For the first time, physicists have performed machine learning on a photonic quantum computer, demonstrating that quantum computers may be able to exponentially speed up the rate at which certain ...

### Magic states offer surprisingly low error rates for quantum computing

(Phys.org)—Quantum computers hold a special allure, as they offer a way to harness quantum phenomena and put it to use to do things that are impossible for ordinary computers. But as powerful as quantum ...

### 'Fibonacci quasiparticle' could form basis of future quantum computers

(Phys.org)—Topological quantum computing (TQC) is a newer type of quantum computing that uses "braids" of particle tracks, rather than actual particles such as ions and electrons, as the qubits to implement ...

### New largest number factored on a quantum device is 56,153

(Phys.org)—Researchers have set a new record for the quantum factorization of the largest number to date, 56,153, smashing the previous record of 143 that was set in 2012. They have shown that the exact same room-t ...

### Majorana fermion: Physicists observe elusive particle that is its own antiparticle

Princeton University scientists have observed an exotic particle that behaves simultaneously like matter and antimatter, a feat of math and engineering that could yield powerful computers based on quantum ...

### Superposition revisited: Proposed resolution of double-slit experiment paradox using Feynman path integral formalism

(Phys.org) —The Schrödinger's Cat thought experiment, published in 1926 by Erwin Schrödinger, may be the most widely-known metaphorical explanation of quantum superposition and collapse. (Superposition is a f ...

### Feynman wasn't joking: Modeling quantum dynamics with ground state wavefunctions

(Phys.org) —Amongst the late Richard Feynman's many prolific and profound contributions to quantum mechanics, the eponymous Feynman clock is perhaps one of the more innovative. Conceived as a solution to the ...

### Towards a global quantum network: Photoelectron trapping in double quantum dots

(Phys.org) —While the journey from today's fledgling quantum computers to a global quantum information network may seem daunting, researchers are continually, and at an accelerating pace, making progress ...
