Publication number: 20230343577Abstract: Aspects of the present disclosure describe devices trapping devices for use in quantum information processing (QIP) architectures, and more particularly, to the use and fabrication of a multi-layer ion trap on shaped glass or dielectric substrate. A method for fabricating the ion trap is described that includes preparing a back surface of the substrate, building a multi-layer stack on the top surface of the substrate, and completing the back etch to break through the substrate and etching through a metal and dielectric in the multi-layer stack to complete the formation of the ion trap. Shaping of the ion trap may also include trap narrowing features, wings, and/or undercutting. An ion trap fabricated using this approach may be used in a QIP system to trap atomic species provided through a hole in the back of the substrate for use as qubits in quantum operations and computations.Type: ApplicationFiled: April 18, 2023Publication date: October 26, 2023Inventors: Jason Madjdi AMINI, Jonathan Albert MIZRAHI, Jeremy Matthew SAGE, James Walker STEERE

Publication number: 20230059264Abstract: The use of multiple ion chains in a single ion trap for quantum information processing (QIP) systems is described. Each chain can have its own set of laser beams with which to implement and operate quantum gates within that chain, where each chain may therefore correspond to a single quantum computing register or core. Operations can be performed in parallel across all of these chains as they can be treated independently from each other. To implement and operate quantum gates between different chains, neighboring chains are merged into a single, larger chain, in which one can perform quantum gates between any of the ions in the larger chain. The combined chains can then be separated again by another shuttling event as needed. To implement and operate quantum gates between ions which do not occupy neighboring chains, swap gates can be used via a sequence of intervening chains.Type: ApplicationFiled: August 18, 2022Publication date: February 23, 2023Inventors: Jungsang KIM, Jonathan Albert MIZRAHI, Jason Madjdi AMINI, Kenneth WRIGHT, Neal PISENTI, Hermann UYS, Ming LI, Michael Lurie GOLDMAN, Jeremy Matthew SAGE, Kai Makoto HUDEK, Yunseong NAM, Nikodem GRZESIAK, Reinhold BLUMEL

Patent number: 4646346Abstract: This integrated message service system provides a user with an indication of which of a plurality of message service systems contain unretrieved messages. This is accomplished by the serving telephone switching system maintaining a translation memory that indicates both the type of message services assigned to each user and the location of unretrieved messages in the assigned message services. The translation memory is updated every time a user creates a new message or accesses a previously stored message.Type: GrantFiled: January 22, 1985Date of Patent: February 24, 1987Assignees: AT&T Company, AT&T Information Systems Inc.Inventors: William D.

Patent number: 4612416Abstract: This integrated message service system provides a user both with an indication of which of a plurality of message service systems contain unretrieved messages and access to these unretrieved messages. This is accomplished by the serving telephone switching system maintaining a translation memory that indicates both the type of message services assigned to each user and the location of unretrieved messages in the assigned message services. The translation memory is updated every time a user creates a new message or accesses a previously stored message. The serving telephone switching system forwards all unretrieved messages from all the message service systems to a user when the user has accessed any one of the message service systems. This eliminates the need for a user to access all assigned message service systems to retrieve messages.Type: GrantFiled: January 22, 1985Date of Patent: September 16, 1986Assignee: AT&T Information Systems Inc.Inventors: William D. Emerson, Deborah J. Hill, Karen C. Loeb, Albert Mizrahi, Charles T. Schlegel, Lowell C. Scott

Patent number: 4091243Abstract: Detection of valid two-out of-N multifrequency signals is realized by employing a microprocessor in conjunction with a controllably adjustable or settable reference threshold level and a plurality of threshold detectors. Under control of the processor, a reference threshold level supplied to the detectors is set to a first prescribed level. Upon detection of a tone which exceeds the first threshold level the processor controllably sets the reference threshold level to a second prescribed level. Detection of two, and only two, tones which are present for at least a minimum prescribed interval are then considered valid.Type: GrantFiled: July 26, 1977Date of Patent: May 23, 1978Assignee: Bell Telephone Laboratories, IncorporatedInventors: Albert Mizrahi, Neal John Moyer, David August Pezzutti
