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. ...
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, ...
Researchers stop and store light for 60 seconds
A team of researchers at Germany's University of Darmstadt has succeeded in causing light to stop and then to be held in place for 60 seconds. In their paper published in the journal Physical Review Letters, the researchers ...
Physicists propose the first scheme to teleport the memory of an organism
In "Star Trek," a transporter can teleport a person from one location to a remote location without actually making the journey along the way. Such a transporter has fascinated many people. Quantum teleportation shares several ...
