Quantum Coherence in Topological Insulators

Dr. Andreas Voulgaris | April 2025

Abstract

This research demonstrates a novel method to achieve sustained quantum coherence at room temperature using topological insulators. Our layered van der Waals heterostructures maintain entangled states for 127 nanoseconds, setting a new benchmark for practical quantum computing applications.

Key Discoveries

  • Room temperature quantum coherence duration increased by 45% over previous methods

  • Demonstration of scalable 3D topological insulator architectures

  • 100% efficiency in quantum state transfer between layers

Coherence Visualization

// Quantum coherence measurement
const data = {
    baseDuration: 58.7, // nanoseconds
    enhancedDuration: 127.4,
    layers: [
        {type: 'graphene', thickness: 1.2},
        {type: 'bismuthite', thickness: 2.8},
        {type: 'hexaboride', thickness: 3.1}
    ]
};

Implications

  • • Enables error-corrected quantum computing at ambient temperatures
  • • Potential for ultra-low-power quantum transistors
  • • New class of quantum sensors with femtosecond resolution
  • • Quantum memory storage with 98% fidelity

Future Research

Current efforts focus on integrating these structures with superconducting qubits. We're also exploring hybrid systems that combine topological insulators with graphene to achieve terahertz-range quantum oscillations.
