Abstract: A novel and useful mechanism of improving the controllability of the electrostatic potential profile and electric field between barrier/control gates separating quantum dots (QD) in a quantum dot array (QDA) and creating elongated double quantum dot array 2D structures each having capability for a continuous tunneling within the array structure. Plunger gates implemented as blind contacts improve electric field control between barrier gates in a quantum dot array. Blind contacts create a dedicated control potential under multiple blind contact electrodes placed on a metal layer of a standard FDSOI process. They function to control potential well depths independently for neighboring quantum dots. Two or more coupled quantum dots within one elongated active area enables interconnection of neighboring quantum dot chains using a conductive semiconductor well. The blind contacts enable the implementation of charge sensors, precise precharge transistors, and linear and 2D quantum dot array.

Abstract: A database management engine provides a user interface that allows users to access and modify employee information in a database. The database includes entries for employees, and each database entry includes identifying information about the associated employee. A user can request to modify data within database entries, for instance in order to update information associated with an employee. Responsive to the request, the database management engine identifies liabilities associated with the database modification stemming from associated tax laws. Based on the identified tax liabilities, the engine computes the aggregate tax liability owed by the employer and/or employee. Before modifying a database entry, the engine modifies the user interface to include interface elements detailing the computed aggregate tax liability. The user explicitly can be required to confirm the database modification in view of the aggregate tax liability.

Abstract: A novel and useful system wiring apparatus and related techniques that address the need to feed power and electronic signals to and from a sample board between the cold, low pressure region in a vacuum chamber and outside room temperature and atmospheric pressure. The wiring apparatus balances electrical resistance with the thermal conductivity of the power and signal conductors. Printed flexible cables are used having an annular sealing region which together with O-rings provide vacuum sealing while allowing electrical signals to pass between integrated circuit(s) inside the vacuum chamber and equipment outside the chamber. A thermal anchor is placed along the printed flexible cable to maintain a desired temperature along the cable. The printed flexible circuits are multilayer with two outer layers serving as an RF shield while two inner layers comprise the signal lines which typically require shielding, electrical isolation from each other and from external electromagnetic fields.

In the disclosed FEM, a thinned flip-chip die, which includes a device region with a metal layer, resides over a module carrier. A mold compound resides over the module carrier, surrounds the thinned flip-chip die, and extends beyond a top surface of the thinned flip-chip die to define an opening over the top surface of the thinned flip-chip die and within the mold compound. A ferrimagnetic portion resides over the top surface of the thinned flip-chip die and within the opening, and a permanent magnetic portion resides over the ferrimagnetic portion and within the opening. Herein, the permanent magnetic portion, the ferrimagnetic portion, and the metal layer of the device region are vertically aligned, and form a circulator vertically stacked with the thinned flip-chip die.

Abstract: A novel and useful quantum computing machine includes classic computing and quantum computing cores. A programmable pattern generator executes instructions that control the quantum core. A pulse generator generates the control signals input to the quantum core to perform quantum operations. A partial readout of the quantum state is re-injected into the quantum core to extend decoherence time. Access gates control movement of quantum particles in the quantum core. Errors are corrected from the readout before being re-injected into the quantum core. Internal and external calibration loops calculate error syndromes and calibrate control pulses input to the quantum core. Control of the quantum core is provided from an external support unit via the pattern generator or retrieved from classic memory where sequences of commands are stored in memory. A cryostat unit functions to cool the quantum computing core to approximately 4 Kelvin.
