Spin shuttling and remote entanglement
Separated spin qubits can share nonlocal quantum correlations.
$$|\Psi^-\rangle=\frac{|01\rangle-|10\rangle}{\sqrt2}$$
Physical intuition
Separated spin qubits can share nonlocal quantum correlations.
Deep dive: physical mechanism
Coherent shuttling or photonic heralding can establish entanglement between distant nodes.
What is measured experimentally?
Bell-state parity correlations and tomography assess remote entanglement.
Assumptions, noise and limitations
Heralding loss, charge noise and transport infidelity constrain performance.
Research and simulation exercise
Simulate entanglement swapping with noisy Bell pairs.
