Variational Quantum Algorithms in the era of Early Fault Tolerance
Siddharth Dangwal, Suhas Vittal, Lennart Maximillian Seifert +2
Quantum computing roadmaps predict the availability of 10,000 qubit devices within the next 3-5 years. With projected two-qubit error rates of 0.1%, these systems will enable certa…
Frequency-noise-insensitive universal control of Kerr-cat qubits
Lennart Maximilian Seifert, Connor T. Hann, Kyungjoo Noh
We theoretically study the influence of frequency uncertainties on the operation of a Kerr-cat qubit. As the mean photon number increases, Kerr-cat qubits provide an increasing lev…
Clifford Assisted Optimal Pass Selection for Quantum Transpilation
Siddharth Dangwal, Gokul Subramanian Ravi, Lennart Maximilian Seifert +3
The fidelity of quantum programs in the NISQ era is limited by high levels of device noise. To increase the fidelity of quantum programs running on NISQ devices, a variety of optim…
Programming an Optical Lattice Interferometer
Lennart Maximilian Seifert, Victor E. Colussi, Michael A. Perlin +2
Programming a quantum device describes the usage of quantum logic gates, agnostic of hardware specifics, to perform a sequence of operations with (typically) a computing or sensing…
Clapton: Clifford-Assisted Problem Transformation for Error Mitigation in Variational Quantum Algorithms
Lennart Maximilian Seifert, Siddharth Dangwal, Frederic T. Chong +1
Variational quantum algorithms (VQAs) show potential for quantum advantage in the near term of quantum computing, but demand a level of accuracy that surpasses the current capabili…
