Protected phase gate for the - qubit using its internal modes
Xanda C Kolesnikow, Thomas B Smith, Felix Thomsen +2
Protected superconducting qubits such as the - qubit promise to substantially reduce physical error rates. However, a key challenge in the field is designing gates for these…
Efficient quantum algorithm for solving differential equations with Fourier nonlinearity via Koopman linearization
Judd Katz, Gopikrishnan Muraleedharan, Abhijeet Alase
Quantum algorithms offer an exponential advantage with respect to the number of dependent variables for solving certain nonlinear ordinary differential equations (ODEs). These algo…
Resolvent-based quantum phase estimation: Towards estimation of parametrized eigenvalues
Abhijeet Alase, Salini Karuvade
Quantum algorithms for estimating the eigenvalues of matrices, including the phase estimation algorithm, serve as core subroutines in a wide range of quantum algorithms, including…
Quantum signal processing without angle finding
Abhijeet Alase
Quantum signal processing (QSP) has emerged as a unifying subroutine in quantum algorithms. In QSP, we are given a function and a unitary black-box , and the goal is to cons…
Erasure conversion in Majorana qubits via local quasiparticle detection
Abhijeet Alase, Kevin D. Stubbs, Barry C. Sanders +1
Quasiparticle poisoning errors in Majorana-based qubits are not suppressed by the underlying topological properties, which undermines the usefulness of this proposed platform. This…
