A quantum information processor (QIP) may include a plurality of quantum registers, each quantum register containing at least one nuclear spin and at least one localized electronic spin. At least some of the quantum registers may be coherently coupled to each other by a dark spin chain that includes a series of optically unaddressable spins. Each quantum register may be optically addressable, so that quantum information can be initialized and read out optically from each register, and moved from one register to another through the dark spin chain, though an adiabatic sequential swap or through free-fermion state transfer. A scalable architecture for the QIP may include an array of super-plaquettes, each super-plaquette including a lattice of individually optically addressable plaquettes coupled to each other through dark spin chains, and separately controllable by confined microwave fields so as to permit parallel operations.

A quantum ticket is defined by a unique serial number; and a set of qubits, each qubit encoding quantum information. The serial number and the set of qubits are distributed only among one or more trusted verifiers who require a tolerance fidelity Ftol in order to authenticate the token, where Ftol represents a minimum percentage of correct outcomes during authentication of the serial number and the set of qubits. The experimental fidelity Fexp for the quantum token is greater than the Ft0i set by the verifiers, so that an honest user of the quantum ticket who achieves Fexp is exponentially likely to be successfully authenticated when seeking authentication by any of the trusted verifiers. The forging fidelity Fforg for the quantum token is less than Ft0i, so that a dishonest user who achieves Fforg and attempts forgery of the quantum ticket is exponentially likely to fail to obtain authentication for his forged ticket.

There is set forth herein a computer program product, computing device, and method for displaying an email message. In one example, a computing device receives an input comprising at least one criterion for redacting email messages; stores the at least one criterion in a configuration of a client computer program; receives an email message having a field, the field comprising a first content; determines whether a condition of at least one of the email message and a current state of the computing device satisfies the at least one criterion stored in the configuration of the client computer program; and, in response to determining that the condition satisfies the at least one criterion, displays a second content in place of the first content in a user interface of the client computer program, wherein the second content is different than the first content.

Illustrative embodiments include a method, system, and computer program product for estimating boot-time memory requirement of a data processing system. A data processing system identifies, using system configuration information associated with the data processing system, a set of components needed for booting up the data processing system. The data processing system determines a dependency of a component identified in the set of components, the component including a memory estimator program. The data processing system determines an ancestry of the component identified in the set of components. The data processing system receives, using the memory estimator program of the component, a boot-time memory requirement of the component. The data processing system calculates a total boot-time memory requirement. The data processing system determines whether an amount of real memory of the data processing system satisfies the total boot-time memory requirement.

A method for evaluating the thermal exposure of a selected metal component which has been exposed to changing temperature conditions is described. The voltage distribution on a surface of the metal component, or on a metallic layer which lies over the component, is first obtained. The voltage distribution usually results from a compositional change in the metal component. The voltage distribution is then compared to a thermal exposure-voltage model which expresses voltage distribution as a function of exposure time and exposure temperature for a reference standard corresponding to the metal component. In this manner, the thermal exposure of the selected component can be obtained. A related device for evaluating the thermal exposure of a selected metal component is also described.

A combustor and combustor liner cap assembly for reducing noise emissions and acoustic dynamics during operation of a gas turbine generally includes a cellular solid media disposed in the combustor liner cap assembly. The cellular solid media absorbs noise emissions and acoustic dynamics, thereby reducing stresses and vibrations on the combustor assembly associated with operation of the gas turbine.

Personal digital assistant devices are provided that query power subsystems to determine a level of battery power currently available for operating processes, and further determine a number of screen display changes that may be effected on a persistent display device at that determined level. If the determined number of screen display changes that may be effected at the determined level of available battery power fails to meet a specified minimum threshold number of images, the processing unit powers down subsystems of the personal digital assistant device and causes a highest listed image of a prioritized list of screen image instances to be displayed on the persistent display device, which persistently displays the image after a loss of power.
