Fermionic Quantum Processors
Framework for universal fermionic quantum processing using globally controlled itinerant fermionic particles in optical lattices.
Core Concepts
Fermionic Quantum Processing
- Particles: Itinerant fermions (neutral atoms)
- Control: Global parameters (tunneling, interaction)
- Universality: Arbitrary fermionic processes achievable
Global Control Paradigm
- Time-dependent: Global parameters varied over time
- Analog-digital hybrid: Continuous + discrete operations
- Scalable: Extends to large lattice systems
Technical Specifications
Platform
- System: Neutral atoms in optical lattices
- Model: Fermi-Hubbard type
- Control: Tunneling and interaction parameters
Capabilities
- Universal: Arbitrary fermionic processes
- Extended models: Long-range couplings supported
- Hybrid: Analog-digital simulation
Implementation
Constructive Protocols
