The vast majority of modern quantum technologies—from quantum cryptography to the quantum internet to the quantum computer—rely on one essential element: the transmission of photons. Two qubits (two atoms, for example) exchange ...
Many complex quantum systems rapidly lose the recognizable patterns of their initial states as their components interact. To describe patterns of regular and chaotic motion in specific systems, physicists can construct a ...
Quantum computers, computer systems that leverage the laws of quantum mechanics, store and process information using qubits (i.e., quantum bits). In many quantum computers, qubits are linked via entanglement, a quantum mechanical ...
Classical computers can temporarily store the information required to perform specific tasks in a short-term memory component known as RAM (random access memory). This component allows computer processors to retrieve information ...
Quantum computers are no longer theoretical concepts. Today, they are being developed to tackle a range of complex problems, including exploring financial risk, modeling complex molecules and optimizing massive logistics ...
Researchers in China have extended the lifetime of entanglement in a room-temperature, solid-state system by up to a factor of 240. Led by Shuo Ren and Rui-Jian Liang at the University of Science and Technology of China in ...
Creating a quantum device often begins by intentionally damaging a crystal. Scientists fire an ultrafast laser pulse into a material, knocking atoms out of place and leaving behind tiny imperfections called vacancies. Far ...
A Stanford team has documented the first direct observation of quantum jumps of sound in a mechanical resonator, completing an arc of scientific exploration that started more than 100 years ago.
Collisions between particles at high energies can sometimes produce new particles and shed light on interactions between the fundamental constituents of matter. Simulating these collisions and their underlying processes could ...
We are continuously sending information to each other, transmitting zeros and ones through a giant network of connected computers and devices. Scientists are now trying to extend this familiar concept of the internet to the ...
