Robustness of Wave-Particle Duality under Unruh Effect

Area of Science:

• Quantum physics
• Quantum information theory
• Relativistic quantum information

Background:

• The Unruh effect predicts that an accelerating observer perceives a thermal bath of particles.
• Quantum coherence is essential for quantum phenomena like superposition and entanglement.
• Wave-particle duality is a fundamental concept in quantum mechanics, describing the dual nature of quantum entities.

Purpose of the Study:

• To investigate the loss of quantum coherence in a uniformly accelerated two-level system (qubit).
• To analyze the impact of acceleration on complementarity relations in quantum circuits.
• To explore decoherence effects induced by the Unruh effect on quantum systems.

Main Methods:

• Considering a uniformly accelerated two-level system in a superposition state.
• Examining quantum coherence decay and interference pattern degradation.
• Analyzing complementarity relations in quantum interferometric and scattering circuits.

Main Results:

• Uniform acceleration leads to a loss of quantum coherence in the qubit.
• The acceleration significantly impacts complementarity relations, degrading interference patterns.
• Decoherence induced by the Unruh effect affects the wave-particle duality of the accelerated qubit.

Conclusions:

• Acceleration is a source of decoherence in quantum systems.
• The Unruh effect has measurable consequences on quantum phenomena like coherence and duality.
• Understanding acceleration-induced decoherence is crucial for quantum information processing in non-inertial frames.
