We present a new quantum computer design using ultracold molecules as qubits. This approach could enable scalable quantum computing with over 10,000 qubits and 100,000 CNOT gates.

Area of Science:

  • Quantum Computing
  • Molecular Physics
  • Atomic Physics

Background:

  • Quantum computers promise to revolutionize computation but require scalable qubit architectures.
  • Existing qubit technologies face challenges in scalability and coherence.

Purpose of the Study:

  • To propose a novel physical realization for a scalable quantum computer.
  • To utilize ultracold diatomic molecules as qubits for quantum information processing.

Main Methods:

  • Employing electric dipole moments of ultracold diatomic molecules as qubits.
  • Arranging molecules in a 1D trap array with electric field gradients for individual addressing.
  • Utilizing electric dipole-dipole interactions for qubit coupling.

Main Results:
