Quantum Photonic Sensing Technology
Quantum sensing represents a paradigm shift in detection technology. By exploiting fundamental quantum mechanical phenomena, we achieve sensitivities impossible with classical approaches.
Why Classical Radar Falls Short
Traditional radar systems have been remarkably successful over 80 years, but face fundamental limitations that cannot be overcome with classical physics.
Standard Quantum Limit
Classical radar is bound by the shot noise limit, setting a fundamental floor on measurement precision.
Stealth Vulnerability
Modern stealth aircraft use radar-absorbing materials that are highly effective against conventional radar.
Jamming Susceptibility
Classical radar can be jammed by broadcasting signals on the same frequencies.
Environmental Degradation
Fog, rain, smoke, and atmospheric turbulence scatter and absorb radar signals.
How Quantum Radar Overcomes These Limits
Quantum radar addresses classical limitations through fundamentally different approaches to signal generation, transmission, and detection.
Quantum Entanglement for Signal Authentication
Photon pairs are generated in an entangled state—their quantum properties correlated in ways that cannot be replicated classically.
Quantum Illumination for Enhanced Detection
A protocol that uses entangled light to detect objects in noisy environments with enhanced signal-to-noise ratios.
Sub-Shot-Noise Measurement
Quantum squeezed states allow uncertainty to be reduced below the standard quantum limit for enhanced precision.
Optical Frequency Operation
We focus on optical-frequency quantum sensing that operates at room temperature with commercially available components.
Types of Quantum Radar Systems
Several distinct approaches to quantum radar have been demonstrated. We focus on architectures closest to practical deployment.
Single-Photon Quantum Radar
Uses extremely low-intensity pulses for detection. Target appears larger at single-photon levels.
Entangled-Photon Optical Radar
Generates entangled photon pairs via SPDC; compares returned signal with stored idler for correlation-based detection.
Quantum LiDAR
Quantum-enhanced laser ranging using entangled or squeezed light for improved range and resolution.
Key Quantum Phenomena
Our technology exploits fundamental quantum mechanical phenomena that have been verified in numerous experiments around the world.
Quantum Entanglement
A correlation between quantum particles stronger than any classical correlation. When two photons are entangled, measuring one instantly determines the properties of the other.
Spontaneous Parametric Down-Conversion
The primary method for generating entangled photon pairs at optical frequencies. A pump photon splits into two correlated photons—signal and idler.
Second-Order Correlation
The g²(τ) function measures the probability of detecting correlated photon pairs. Strong correlations are the fundamental measurement for quantum detection.
