The Challenge

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.

SQL Δn ≥ √n

Standard Quantum Limit

Classical radar is bound by the shot noise limit, setting a fundamental floor on measurement precision.

σ→0

Stealth Vulnerability

Modern stealth aircraft use radar-absorbing materials that are highly effective against conventional radar.

SNR→0

Jamming Susceptibility

Classical radar can be jammed by broadcasting signals on the same frequencies.

I = I₀e^(-αz)

Environmental Degradation

Fog, rain, smoke, and atmospheric turbulence scatter and absorb radar signals.

The Quantum Solution

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.

Primary Focus

Single-Photon Quantum Radar

Uses extremely low-intensity pulses for detection. Target appears larger at single-photon levels.

SPDC Delay
Core Development

Entangled-Photon Optical Radar

Generates entangled photon pairs via SPDC; compares returned signal with stored idler for correlation-based detection.

Δz < λ/2 Squeezed
Commercial Priority

Quantum LiDAR

Quantum-enhanced laser ranging using entangled or squeezed light for improved range and resolution.

Core Physics

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.

χ²

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.

τ

Second-Order Correlation

The g²(τ) function measures the probability of detecting correlated photon pairs. Strong correlations are the fundamental measurement for quantum detection.
