OptoQuantum tracks the frontier of photonic quantum systems — from entangled photon sources to fault-tolerant optical processors reshaping computing, communication and sensing.
We track every dimension of optical quantum technology — from foundational physics to deployed infrastructure.
Photon states, entanglement generation via SPDC, squeezed light, Bell-state measurements, and the quantum optics formalism powering modern experiments.
Linear-optical circuits, boson sampling, integrated photonic chips, and hybrid quantum-classical processors achieving computational advantage.
QKD protocols, quantum repeaters, satellite-based entanglement distribution, and the architecture of the coming global quantum internet.
The Jiuzhang 3.0 experiment deployed 255 squeezed-light modes through a 1,456-port interferometer, completing Gaussian boson sampling in 1 microsecond — a task that would take every classical supercomputer on Earth longer than the age of the universe.
China's Micius satellite demonstrated intercontinental quantum key distribution — two ground stations separated by 7,600 km exchanged provably secure cryptographic keys through space, marking the birth of quantum-safe global communications.
IBM's newest processor achieves a logical qubit with less than 10⁻⁶ error rate per gate using surface code error correction.
MIT and Caltech embedded NV-diamond emitters into CMOS-compatible silicon photonics, generating on-demand photons at 300 K.
Delft University and NIST demonstrated quantum state teleportation over a trans-national fiber network, setting a new record.
Room-temperature OPM sensors with femtotesla sensitivity enable millisecond-resolution brain mapping without cryogenics.
Curated quantum optics research highlights, pre-prints, and conference coverage — delivered every Monday.
