摘要： A device for controlling trapped ions includes a substrate. A structured first metal layer is disposed over the substrate. The structured first metal layer forms electrodes of an ion trap configured to trap ions in a space above the structured first metal layer. The structured first metal layer is formed of a multilayer stack. The multilayer stack includes an electrically conductive layer of a first material and a mechanical stabilization layer of a second material. The second material has an elastic modulus greater than the elastic modulus of the first material and/or the second material has a yield strength greater than the yield strength of the first material.

摘要： A method of generating a verification code includes generating a plurality of first photons and a plurality of second photons that are entangled in a first basis, which is time, and entangled in a second basis comprising a first and second state. The plurality of first photons are provided to a first device where the arrival time and an associated first or second state of the plurality of first photons are measured. An ordered list of the measured time of arrival of the plurality of first photons are generated at the first device. The plurality of second photons are provided to a second device. A time of arrival and an associated first or second state of the plurality of second photons are measured at the second device. An ordered list of the measured time of arrival of the plurality of second photons are generated at the second device. The ordered list of the time of arrival of the plurality of first photons and the ordered list of the measured time of arrival of the plurality of second photons are processed to determine time-of-arrival matches between the ordered list of the time of arrival of the plurality of first photons and the ordered list of the measured time of arrival of the plurality of second photons. The first or second state values associated with the time-of-arrival matches is determined. A verification code with at least some of the determined first or second state values associated with the time-of-arrival matches is generated.

摘要： A qubit device includes a crystal immobilized on a substrate and in contact with electrodes. The crystal exhibits a charge pair symmetry and with an electron current moving clockwise, counter clockwise, or both. The current in can be placed in a state of superposition wherein the current is unknown until it is measured, and the direction of the current is measured to produce a binary output corresponding to a logical zero or a logical one. A state of the qubit device is monitored by measuring a voltage, a current, or a magnetic field and assigning a superposition or base state depending on a threshold value.
