Abstract: A method of correcting for crosstalk in thermo-optics phase shifters (TOPS) integrated on a substrate, includes, in part, determining a first value representative of an amount of electrical power applied to a heater associated with a first TOPS causing a known phase shift in an optical signal passing through the first TOPS' associated waveguide; determining a second value representative of a time constant of the first TOPS; determining a third value representative of an amount of electrical power applied to a heater associated with a second TOPS causing a known phase shift in an optical signal passing through the waveguide associated with the first TOPS; determining a multitude of thermal couplings between a multitude of heaters, waveguides and positions in the substrate using one or more of the first, second and third values; and making a correction associated with the crosstalk in accordance with the thermal couplings.

Abstract: Quantum Phased Array(s) of emitters and receivers that generate, modulate, emit, receive, and detect any quantum field. Quantum phased arrays include particle source(s) sourcing any quantum field, transmit modulator element(s) modulating any quantum observable and the associated quantum field, emitting elements radiating one or more quantum fields spatiotemporally, a propagation medium with one or more modulator elements for complete control of the quantum field, receiver(s) receiving one or more quantum fields, receive modulator element(s) modulating any quantum observable and the associated quantum field, detector(s) resolving one or more received quantum fields. Quantum metrology, communication and computing systems including quantum phased arrays are detailed for leveraging quantum field engineering functionality (complete control of one or more wavefunctions of one or more particles in any one or more orthonormal bases) of quantum phased arrays for quantum metrology, communication and computing applications.
