When we think about a diamond, we often think about a material whose value comes from its perfection. In my research, however, I am interested in something almost opposite: the tiny imperfections inside diamonds. These […]

Most of us recognize basic phases of matter and their properties: solids maintain their shape, liquids flow freely with constant volume, and gases expand to fill their container. Quantum phases, on the other hand, are […]
Physicists in the Department of Physics at the University of Oxford have used a hybrid quantum computer, made up of qubits and quantum oscillators, to observe the Aharonov–Bohm effect in a quantum simulation. The effect […]
Every black hole hides a question at its center. Einstein’s theory predicts that whatever falls in is crushed into a singularity, a point of infinite density where the theory itself breaks down. Most physicists expect […]
For highly fragile quantum information systems, the ability to store quantum information is vital—but also challenging. Quantum information is transported in particles of light called photons, which often must be temporarily paused (or “stored”) while […]
University of Glasgow researchers are part of an international collaboration that could lead to a new generation of quantum sensors. The team, which included researchers from the University of Tokyo, University of Glasgow, University of […]
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 effect that connects […]
Molecules can be placed in a wide variety of quantum states. How can these states be distinguished in measurements when theoretical models are unreliable? Which excitation process lies behind which measurement signal? Click to rate […]
Quantum technologies are considered key technologies of the future. However, research in this field requires not only scientific expertise but sometimes also highly specialized laboratory conditions. Bose–Einstein condensates are a remarkable example, in which atoms […]
In some materials, physical properties don’t emerge from their individual particles, but from the collective behavior of their quantum spins. Now, researchers led by Pengcheng Dai at Rice University in the U.S. have discovered that […]
