Collective behavior is an unusual phenomenon in condensed-matter physics. When quantum spins interact together as a system, ...
Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works extremely well in its own domain: Quantum theory explains how atoms and ...
With only two levels of superposition, the qubits used in today's quantum communication technologies have limited storage space and low tolerance for interference. Engineering's hyperdimensional ...
Our universe plays by certain rules, which originate from different branches of physics. But sometimes the rules seem ...
Quantum dots and quantum wells represent pivotal semiconductor nanostructures whose quantum confinement effects yield discrete energy spectra and highly tunable optical and electronic properties.

Scientists stumble on a bizarre new quantum state that defies logic
Physicists working at ultra-low temperatures have stumbled onto a quantum phase that should not exist according to the usual ...
Physicist Paul Davies’s Quantum 2.0: The past, present and future of quantum physics ends on a beautiful note. “To be aware of the quantum world is to glimpse something of the majesty and elegance of ...
Light is usually described using quantum mechanics when phenomena like entanglement enter the picture. But a new paper shows ...
Researchers at Penn Engineering have created a chip that outstrips the security and robustness of existing quantum communications hardware. Their technology communicates in “qudits,” doubling the ...
