Entanglement-enhanced quantum rectification.

Quantum mechanics dictates the band-structure of materials that is essential for functional electronic components. With increased miniaturization of devices it becomes possible to exploit the full potential of quantum mechanics through the principles of superpositions and entanglement. We propose a new class of quantum rectifiers that can leverage entanglement to dramatically increase performance by coupling two small spin chains through an effective double-slit interface. Simulations show that rectification is enhanced by several orders of magnitude even in small systems and should be realizable using several of the quantum technology platforms currently available.
