A Meissner-Effect Transition-Edge-Sensor (ME-TES) microcalorimeter device may have one or more microcalorimeter elements, each including an absorber body composed of a superconductive element that is arranged to absorb incoming photons or radiative particles. A planar pickup coil substantially surrounds the absorber body and is located within a magnetic sensing distance of the absorber body. Absorption of incoming photons or radiative particles increases the temperature of the superconductive element, resulting in a change in magnetic flux through the superconductive element. This change in magnetic flux induces a transient electric current in the planar pickup coil that may be sensed using a readout circuit. A method is provided for fabricating an ME-TES microcalorimeter device.

A quantum computing device that includes a plurality of semiconductor adiabatic qubits is described herein. The qubits are programmed with local biases and coupling terms between qubits that represent a problem of interest. The qubits are initialized by way of a tuneable parameter, a local tunnel coupling within each qubit, such that the qubits remain in a ground energy state, and that initial state is represented by the qubits being in a superposition of |0&#x3e; and |1&#x3e; states. The parameter is altered over time adiabatically or such that relaxation mechanisms maintain a large fraction of ground state occupation through decreasing the tunnel coupling barrier within each qubit with the appropriate schedule. The final state when tunnel coupling is effectively zero represents the solution state to the problem represented in the |0&#x3e; and |1&#x3e; basis, which can be accurately read at each qubit location.
