Abstract: Systems and methods for calibrating and initializing a system comprising a first qubit, a second qubit, and a coupler are provided. A method of initializing the system can include calibrating the system; providing a first idle resonance frequency of the first qubit and a second idle resonance frequency of the second qubit; providing the first bias for the first idle resonance frequency and the second bias for the second idle resonance frequency; determining a value of the third resonance frequency at which a difference between the first degree of coupling and the second degree of coupling is minimized, when the first resonance frequency is the first idle resonance frequency and the second resonance frequency is the second idle resonance frequency; and providing the third bias according to the determined value of the third resonance frequency.

Abstract: An electrochemical cell thermal testing fixture and related apparatus are provided for connection to a battery cycler. The thermal testing fixture comprises a temperature-controlled plate configured to contact a surface of a cylindrical electrochemical cell, and a cell stand, comprising positive and negative contacts, configured to receive the cell. In some examples, the negative contact is configured to contact the sidewall of a cylindrical cell. An electrochemical cell thermal testing fixture system is also provided, comprising a plurality of individually controlled thermal testing fixtures coupled together.

Abstract: Methods, systems and apparatus for benchmarking quantum computing hardware. In one aspect, a method includes defining an initial circuit configured to operate on an array of qubits, wherein the initial circuit comprises multiple instances of the two-qubit gate, wherein each instance of the two-qubit gate performs a same operation on a respective pair of neighboring qubits in the array; partitioning the initial circuit into multiple layers, wherein instances of the two-qubit gate in a respective layer can be implemented in parallel; for each of the multiple layers: constructing benchmarking circuits for the layer, wherein each benchmarking circuit for the layer comprises one or more cycles of quantum gates, each cycle comprising: the layer of instances of the two-qubit gate, and a plurality of single qubit gates; implementing the constructed benchmarking circuits to obtain experimental benchmarking data; and adjusting control parameters of the control model using the experimental benchmarking data.

Abstract: A touchless compartmentalized cooler includes set of individual refrigeration cubbies with private/securable access for individual users. It allows a person to access a cubby to place food/beverages into a single cubby with no other people's items. It is lockable by the user to keep their items secure until they unlock the cubby to access their items or permanently remove them. The use of the touchless compartmentalized cooler can be entirely contactless by using the mobile app associated with the touchless compartmentalized cooler or can be accessed on the single control panel on, or near, the touchless compartmentalized cooler.

Abstract: The present disclosure relates to methods for treating hair with lactones. The lactones form a covalent thio-ester bond with free thiols groups on chemically treated hair, and thereby impart a “repairing” or “conditioning” effect to the hair, for example, by making the hair more hydrophobic. Typically, after hair has been treated with a composition comprising one or more reducing agents that reduce disulfide bonds of hair to free thiols, a composition comprising one or more lactones is applied to the hair and the one or more lactones react with the free thiols to form a covalent thio-ester bond. Treatment with the lactones prevents reversion of the repaired bonds to their free thiol state after a single application.

Abstract: A miter saw includes a base, a horizontal table supported by the base, an arm pivotably coupled to the base at a rear pivot point configured to permit the arm to pivot about a horizontal axis, a circular saw blade arbor supported by the arm at a location spaced forward from the rear pivot point, and a circular saw blade supported by and concentric with the arbor. The saw blade is configured to be driven to cut a workpiece on the horizontal table. The rear pivot point permits the blade to move along an arc in a vertical plane perpendicular to the horizontal table. Between a rear edge of the arbor and a rear edge of the blade, the arm extends substantially above the height of the blade to allow substantially the entire blade area rearward of the rear edge of the arbor to be available for cutting the workpiece.

Abstract: A bicycle crank assembly is provided having a sprocket flange and a pedal crank arm, the sprocket flange being coaxially affixed to a bicycle crank shaft, the first end of the pedal crank arm being coaxially mounted about a laterally projecting generally cylindrical shaft member of the sprocket flange, a pedal bolt being affixed proximate a distal end of the pedal crank arm, and the pedal crank arm being affixed proximate the perimeter of the sprocket flange generally opposite the pedal bolt with a 145 degree offset about the axis of rotation of the bicycle crank shaft to increase the distance from the drive bolt to the pedal and to increase the leverage and power imparted to the bicycle crank assembly. A sprocket is coaxially affixed to the sprocket flange.
