Q-Profile: Profiling Tool for Quantum Control Stacks applied to the Quantum Approximate Optimization Algorithm
Koen J. Mesman, Francesco Battistel, Edgar Reehuis +5
Scaling up the number of qubits and speeding up the execution of quantum algorithms are important steps towards reaching quantum advantage. This poses heavy demands particularly on…
Real-Time Decoding for Fault-Tolerant Quantum Computing: Progress, Challenges and Outlook
Francesco Battistel, Christopher Chamberland, Kauser Johar +5
Quantum computing is poised to solve practically useful problems which are computationally intractable for classical supercomputers. However, the current generation of quantum comp…
Logical-qubit operations in an error-detecting surface code
J. F. Marques, B. M. Varbanov, M. S. Moreira +10
We realize a suite of logical operations on a distance-two logical qubit stabilized using repeated error detection cycles. Logical operations include initialization into arbitrary…
A hardware-efficient leakage-reduction scheme for quantum error correction with superconducting transmon qubits
Francesco Battistel, Boris M. Varbanov, Barbara M. Terhal
Leakage outside of the qubit computational subspace poses a threatening challenge to quantum error correction (QEC). We propose a scheme using two leakage-reduction units (LRUs) th…
High-fidelity controlled-Z gate with maximal intermediate leakage operating at the speed limit in a superconducting quantum processor
V. Negîrneac, H. Ali, N. Muthusubramanian +9
We introduce the sudden variant (SNZ) of the Net Zero scheme realizing controlled- (CZ) gates by baseband flux control of transmon frequency. SNZ CZ gates operate at the speed l…
Leakage detection for a transmon-based surface code
B. M. Varbanov, F. Battistel, B. M. Tarasinski +4
Leakage outside of the qubit computational subspace, present in many leading experimental platforms, constitutes a threatening error for quantum error correction (QEC) for qubits.…
Spectral Quantum Tomography
Jonas Helsen, Francesco Battistel, Barbara M. Terhal
We introduce spectral quantum tomography, a simple method to extract the eigenvalues of a noisy few-qubit gate, represented by a trace-preserving superoperator, in a SPAM-resistant…
A fast, low-leakage, high-fidelity two-qubit gate for a programmable superconducting quantum computer
M. A. Rol, F. Battistel, F. K. Malinowski +8
A common approach to realize conditional-phase (CZ) gates in transmon qubits relies on flux control of the qubit frequency to make computational states interact with non-computatio…
