Arbitrary Quantum Operations With A Common Coupled Resonator

View page
US Patent:
7498832, Mar 3, 2009
Filed:
Aug 3, 2007
Appl. No.:
11/833902
Inventors:
James E. Baumgardner - Ellicott City MD, US
Aaron A. Pesetski - Gambrills MD, US
Assignee:
Northrop Grumman Systems Corporation - Los Angeles CA
International Classification:
H03K 19/195
US Classification:
326 7, 326 3, 326 6
Abstract:
A quantum logic gate is formed from multiple qubits coupled to a common resonator, wherein quantum states in the qubits are transferred to the resonator by transitioning a classical control parameter between control points at a selected one of slow and fast transition speeds, relative to the characteristic energy of the coupling, whereby a slow transition speed exchanges energy states of a qubit and the resonator, and a fast transition speed preserves the energy states of a qubit and the resonator.

Filed:
Apr 28, 2008
Appl. No.:
12/111035
Inventors:
Quentin P. Herr - Ellicott City MD, US
James E. Baumgardner - Odenton MD, US
Aaron A. Pesetski - Gambrills MD, US
Assignee:
Northrop Grumman Corporation - Los Angeles CA
International Classification:
H03K 19/195
US Classification:
326 4, 327367
Abstract:
The disclosure relates to a method for providing a logic circuit element. The method includes arranging a series of Josephson junctions between a first Josephson junction and a second Josephson junction, the first Josephson junction having a first critical current (I) and the second Josephson junction having a second critical current (I); providing a working current to the first Josephson junction, the working current transmitting to the second Josephson junction through the series of the Josephson junctions; wherein the working current is sufficiently high to trigger the second Josephson junction while sufficiently low to not disturb super-conductivity of the series of intermediate Josephson junctions.

Quantum Gate Operations With A Common Coupled Resonator

US Patent:
7893708, Feb 22, 2011
Filed:
Mar 29, 2010
Appl. No.:
12/748923
Inventors:
James E. Baumgardner - Odenton MD, US
Aaron A. Pesetski - Gambrills MD, US
Assignee:
Northrop Grumman Systems Corporation - Los Angeles CA
International Classification:
H03K 19/195
US Classification:
326 7, 326 2, 326 3, 326 6
Abstract:
Systems and methods are provided for performing a quantum gate operation. A first classical control parameter is associated with a first qubit and coupled to a resonator. The first classical control parameter is transitioned from a first control value to a second control value. The first classical control parameter is returned from the second control value to the first control value via an adiabatic sweep operation, as to permit a transfer of energy between the first qubit and the resonator that causes a change in the quantum state of the qubit and resonator.

Method And Apparatus For Controlling Qubits With Single Flux Quantum Logic

US Patent:
7969178, Jun 28, 2011
Filed:
May 29, 2008
Appl. No.:
12/128906
Inventors:
John Xavier Przybysz - Severna Park MD, US
James E. Baumgardner - Odenton MD, US
Aaron A. Pesetski - Gambrills MD, US
Donald Lynn Miller - Export PA, US
Ouentin P. Herr - Ellicott City MD, US
Assignee:
Northrop Grumman Systems Corporation - Los Angeles CA
International Classification:
H03K 19/195
US Classification:
326 5, 331107 S, 333 99 S
Abstract:
In one embodiment, the disclosure relates to a method and apparatus for controlling the energy state of a qubit by bringing the qubit into and out of resonance by coupling the qubit to a flux quantum logic gate. The qubit can be in resonance with a pump signal, with another qubit or with some quantum logic gate. In another embodiment, the disclosure relates to a method for controlling a qubit with RSFQ logic or through the interface between RSFQ and the qubit.

Method And Apparatus For Matched Quantum Accurate Feedback Dacs

View page
US Patent:
7982646, Jul 19, 2011
Filed:
Jul 31, 2008
Appl. No.:
12/184204
Inventors:
Quentin P. Herr - Ellicott City MD, US
Aaron A. Pesetski - Gambrills MD, US
John X. Przybysz - Severna Park MD, US
Donald L. Miller - Export PA, US
Assignee:
Northrop Grumman Systems Corporation - Los Angeles CA
International Classification:
H03M 3/00
US Classification:
341143, 341133
Abstract:
A second order superconductor delta-sigma analog-to-digital modulator having an input for receiving an analog signal, a first integrator coupled to the input, a second integrator cascaded with the first integrator, and a quantum comparator digitizing output from the second integrator reduces quantization noise by providing matched quantum accurate DACs in a feedback loop between output from the quantum comparator and input to the first integrator. The matched quantum accurate feedback DACs produce identically repeatable voltage pulses, may be configured for multi-bit output, may be time-interleaved to permit higher clocking rates, and may be employed in a balanced bipolar configuration to allow inductive input coupling. Bipolar feedback is balanced when gain of a first DAC exceeds gain of a matched, opposite polarity DAC by the amount of implicit feedback from the comparator into the second integrator.

Quantum Logic Gates Utilizing Resonator Mediated Coupling

US Patent:
8022722, Sep 20, 2011
Filed:
Jun 4, 2010
Appl. No.:
12/794439
Inventors:
Aaron A. Pesetski - Gambrills MD, US
James E. Baumgardner - Odenton MD, US
Assignee:
Northrop Grumman Systems Corporation - Los Angeles CA
International Classification:
H03K 19/195
US Classification:
326 7, 326 3, 326 6
Abstract:
Systems and methods are provided for performing a quantum gate operation. A first classical control parameter, configured to tune an associated frequency of a first qubit, is adjusted from a first value to a second value. The first value is selected such that the first qubit is tuned far from a characteristic frequency of an associated resonator, and the second value is selected such that the first qubit is tuned near to the characteristic frequency of the resonator. A second classical control parameter, configured to tune an associated frequency of a second qubit, is adjusted from a third value to a fourth value. The third value is selected such that the second qubit is tuned far from the characteristic frequency of the resonator. The first classical control parameter is returned to the first value. The second classical control parameter is returned to the third value.
