Abstract: There is described a method of manufacturing a substrate for an optoelectronic device. The method has the steps of: supporting a first layer of a first crystalline material on a second layer of a second crystalline material different from said first crystalline material thereby exposing crystalline defects at a surface of said first layer; etching said first layer using first etching conditions, at least some of said crystalline defects expanding into pores running from said surface of the first layer towards said second layer; and heating said first and second layers up to a first temperature for a first period of time within a given environment, said heating transforming said pores into nanovoids attracting at least some of said crystalline defects away from said surface. In some embodiments, the method has a step of reheating the layers or a step of forming a pore containing region within the first layer.

Abstract: Time-to-digital converter (TDC) using multiple Vernier in a cascaded architecture reduces the timing jitter by decreasing the number of the ring oscillator cycles during the measurement processes. Time-to-digital converter (TDC) measurements using a third oscillator for the second Vernier process has significant advantages compared to changing the period of the second oscillator during the measurement cycle. The Vernier architecture described herein may operate with faster oscillators, reducing the number of intervals before converging and leading to a lower time conversion and a better timing jitter Adding multiple cascaded Vernier interpolation may further improve the TDC measurement resolution while having only a small increment of time required to resolve the time interval calculations.

Abstract: A quantum circuit called a “qumon” is provided to cancel unwanted ZZ interaction in a superconducting qubit architecture. The qumon qubit has a high coherence, and a positive anharmonicity that may be tuned to cancel the negative anharmonicity in a coupled qubit, such as a transmon qubit. The qumon has three parallel branches, in which are a shunt capacitor; a Josephson junction having weighted energy level and capacitance; and several Josephson junctions in series. The weight is chosen to provide the desired anharmonicity, and the transverse flux noise and transverse charge noise each decrease in proportion to the number of the Josephson junctions in series. Because unwanted ZZ interactions are canceled, qumon qubits and transmon qubits may be capacitively coupled in an alternating pattern to provide a surface code in which these interactions are canceled in an extensible way.

Abstract: A magnetic field causing a difference of energy level between different spin states in the sample can be applied, a spin transition in the material can be triggered by exposing the sample to electromagnetic radiation of an energy level corresponding to the difference in energy level between the different spin states, a sensing surface of a superconducting element can be exposed to a magnetic field of the spins in the sample, the spin transition can cause, via kinetic inductance, a change in electromagnetic waves carried by the superconducting element which can be detected. A magnetic field component normal to the sensing surface, below a certain magnetic field threshold, can be applied to favor sensitivity.

Abstract: Method and apparatus for determining that a pressure field is applied on a structure. A plurality of acoustic waves are generated within the structure using at least one wave generator and a plurality of measurements of the acoustic waves is taken using at least one wave sensor. A pressure field applied to a surface of the structure is determined by processing at least two of the plurality of measurements. The wave generator and the wave sensor may be piezoelectric elements, which may alternate between acting as the wave generator and the wave sensor. Processing the measurements may comprise obtaining a differential measurement value and comparing the value to a threshold. Determining that the pressure field is applied may comprise processing the measurements using a model based on acoustic wave propagation or experimental results. The processing may provide a mapping of the pressure field of an object on the structure.

Abstract: An actuator system for articulated mechanism may have a fluid actuator having a displaceable member operating an output configured to apply an output force to the articulated mechanism. A fluid system may be in fluid communication with the fluid actuator to supply the fluid actuator with motive fluid to contribute to the output force. The fluid system may include a pressure reservoir configured for storing fluid, a pumping device for controlling a pressure of the fluid in the reservoir, and a circuit for directing the fluid from the reservoir to the fluid actuator. An actuator device may be operatively connected to the fluid actuator to apply a variable force to the displaceable member to contribute to the output force.
