Quantum computer emulated by a classical system
(Phys.org)—Quantum computers are inherently different from their classical counterparts because they involve quantum phenomena, such as superposition and entanglement, which do not exist in classical digital computers. ...
Quantum gravity's tangled time
The theories of quantum mechanics and gravity are notorious for being incompatible, despite the efforts of scores of physicists over the past fifty years. However, recently an international team of researchers led by physicists ...

Physicists propose a second level of quantization for quantum Shannon theory
Information theory, which was developed by Claude Shannon starting in the late 1940s, deals with questions such as how quickly information can be sent over a noisy communications channel. Both the information carriers (e.g., ...
A new kind of quantum computer
Quantum mechanics incorporates some very non-intuitive properties of matter. Quantum superposition, for example, allows an atom to be simultaneously in two different states with its spin axis pointed both up and down, or ...

Could Schrödinger's cat exist in real life? Our research may soon provide the answer
Have you ever been in more than one place at the same time? If you're much bigger than an atom, the answer will be no.

143 is largest number yet to be factored by a quantum algorithm
(Phys.org) -- While factoring an integer is a simple problem when the integer is small, the complexity of factorization greatly increases as the integer increases. When the integer grows to more than 100,000 or so digits, ...
New half-meter record for quantum superposition at macroscopic level
A team of researchers working at Stanford University has extended the record for quantum superposition at the macroscopic level from one to 54 centimeters. In their paper published in the journal Nature, the team describes ...
Of Einstein and entanglement: Quantum erasure deconstructs wave-particle duality
(Phys.org)—Quantum physics presents several counterintuitive features, including entanglement, tunneling and – as demonstrated in double-slit experiments – wave-particle duality. When studying wave-particle duality, ...
Research pair offer a way to put a living organism into superposition state
(Phys.org)—A pair of physicists, one with Tsinghua University in China, the other with Perdue University in the U.S. has come up with what they believe is a viable way to cause a living organism to be in two places at the ...
