NantQ entangled photon sources are deployed across the three pillars of quantum technology and an expanding ecosystem of photonic communication systems.
Photonic quantum computing uses individual photons as qubits, manipulated through linear optical elements, beam splitters, and phase shifters. NantQ's high-purity entangled photon sources provide the deterministic photon pairs required for:
Our QLS and QEPS systems provide the telecom-wavelength entangled pairs with visibility V = 0.96, enabling high-fidelity quantum operations essential for error-corrected photonic processors.
Full system for multi-photon experiments
OEM integration into photonic processors
Rapid prototyping and algorithm testing
Correlated photon pairs enable measurements beyond the classical noise floor.
Image reconstruction using spatially correlated photon pairs where only one photon interacts with the object.
Enhanced target detection in noisy environments using entangled photon probes.
Quantum-enhanced OCT with improved axial resolution using broadband SPDC sources.
Quantum sensing exploits the correlations between entangled photon pairs to achieve measurement sensitivities impossible with classical light. NantQ's broadband SPDC sources with bi-photon bandwidth ≥ 2 nm are ideal for:
The high heralding efficiency of NantQ sources ensures that every detected idler photon reliably heralds the presence of its signal twin, maximizing the quantum advantage in sensing protocols.
Quantum Key Distribution (QKD) provides information-theoretically secure communication by encoding keys in quantum states of light. NantQ's telecom C-band entangled sources are purpose-built for deployment over existing fiber-optic infrastructure:
Operating at 1550 nm in the low-loss fiber window, NantQ sources achieve maximum transmission distance while maintaining the high visibility needed for low QBER in deployed quantum networks.
NantQ quantum sources integrate into the growing ecosystem of optical communication and space-based networking platforms:
Next-generation inter-satellite and ground-link laser terminals are being deployed at industrial scale. NantQ sources enable quantum-secured channels over these optical backbones.
Military and intelligence communities are adopting directed-energy photonics for ISR and communications. QKD layers quantum resilience onto these tactical networks.
Broadband mega-constellations with laser crosslinks are scaling globally. Quantum-secured feeder links protect these networks from future cryptographic threats.
