Over the past decades, quantum physicists and engineers have developed numerous technologies that harness the principles of quantum mechanics to push the boundaries of classical information science.

A new chip-based quantum memory uses nanoprinted “light cages” to trap light inside atomic vapor, enabling fast, reliable storage of quantum information. The structures can be fabricated with extreme ...

Quantum computers, computing systems that process information using quantum mechanical effects, could outperform classical computers on some computational tasks. These computers rely on qubits, the ...

The original version of this story appeared in Quanta Magazine. It’s not easy to study quantum systems—collections of particles that follow the counterintuitive rules of quantum mechanics.

It’s not easy to study quantum systems — collections of particles that follow the counterintuitive rules of quantum mechanics. Heisenberg’s uncertainty principle, a cornerstone of quantum theory, says ...

The group of Prof. Xiao-Song Ma at Nanjing University has demonstrated the faithful teleportation from telecom photons to erbium-ion based quantum memory. The key elements for this achievement are the ...

Physicists have used Doppler-shifted nuclear resonant absorbers to form a nuclear frequency comb, enabling a quantum memory in the notoriously difficult X-ray range. Light is an excellent carrier of ...

IBM Corp. today revealed its expected roadmap for building the world’s first large-scale, fault-tolerant quantum computer, which would enable scaling up quantum computing for real-world practical ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...
