The Leak Becomes the Link
Two superconducting qubits reached an entangled steady state through controlled dissipation instead of losing coherence to it.
Summary
Two superconducting qubits reached an entangled steady state through controlled dissipation instead of losing coherence to it.
University of Illinois Urbana-Champaign and University of Chicago researchers demonstrated a long-predicted route to remote entanglement in which relaxation drives two superconducting qubits toward a shared steady state. Their synthetic-squeezing technique uses a one-way waveguide and external drives to engineer the environment that normally destroys fragile quantum correlations. The laboratory result involves two qubits and does not itself demonstrate an arbitrarily long network, but it points toward entanglement that can be maintained without preparing a state and physically transporting it.
Why it matters
Two superconducting qubits reached an entangled steady state through controlled dissipation instead of losing coherence to it.
