Iran to perform 2nd phase of quantum cryptography experiment

The head of the Atomic Energy Organization of Iran (AEOI) has ordered the start of the second phase of the open space quantum cryptography project during a tour of the country’s Center for Quantum Technologies.

Quantum fridge works by superposing the order of events

Ever tried defrosting your dinner by popping it in one identical freezer after another? Strange as it sounds, recent studies of indefinite causal order — in which different orders of events are quantum superposed — suggest this could actually work for quantum systems.

A method to simulate strongly correlated phases of quantum gauge theories

Quantum gauge theories are mathematical constructs that are typically used by physicists to describe subatomic particles, their associated wave fields and the interactions between them.

Single atoms sit still on a hot plate, may yield new quantum tech

Lasers? Individual atoms trapped next to hot surfaces? Lots of dense text about degrees of freedom and stuff? I have found the afterlife, and it is a big quantum optics experiment.

Physicists measure energy difference between two quantum states

A physicist in New Zealand has measured the energy difference between two quantum states in a helium atom.

Researchers manipulate width of GNRs to create quantum chains

Researchers at EMPA (Swiss Federal Laboratories for Materials Science and Technology), along with colleagues from the Max Planck Institute for Polymer Research in Mainz and other partners, have succeeded in precisely controlling the properties of graphene nano-ribbons (GNRs) by specifically varying their shape.

Iran achieves secure quantum communications technology

The new technology of Iran in the field of secure quantum communications was unveiled on Wednesday in Iranian National Laser Center (INLC).

World's first quantum computer for chemical bonds simulation

An international team led by an Australian physicist demonstrated the world's first multi-qubit quantum chemistry calculation based on a system of trapped ions.

Designer diamonds could one day help build quantum Internet

A new kind of artificial diamond is a cut above the rest for quantum memory.

Tiny version of this physics toy revealing quantum secrets

A simple toy is helping scientists understand new details of a mysterious quantum process.

Quantum drum can vibrate and stand still at the same time

Scientists have built a tiny drum that both vibrates and remains still when struck by a drumstick made of light. The feat blurs the lines between the quantum world and the visible world defined by classical physics.

Quantum physicists achieve entanglement record

Entanglement is of central importance for the new quantum technologies of the 21st century.

New chip technology can lead to better quantum computing power

An international team, including Chinese researchers, has demonstrated a large-scale integrated quantum photonic circuit, which may pave the way for manufacturing massive components for the realization of an optical quantum computer, according to a study recently released by the University of Bristol.

Google moves toward quantum supremacy with 72-qubit computer

Researchers from Google are testing a quantum computer with 72 quantum bits, or qubits, scientists reported at a meeting of the American Physical Society — a big step up from the company’s previous nine-qubit chip.

Quantum computers 'one step closer'

Quantum computing has taken a step forward with the development of a programmable quantum processor made with silicon.
