Pontryagin Maximum Principle for Rydberg-blockaded state-to-state transfers: A semi-analytic approach
Federico Alberto Astolfi, Sven Jandura, Guido Pupillo
We study time-optimal state-to-state control for two- and multi-qubit operations motivated by neutral-atom quantum processors within the Rydberg blockade regime. Block-diagonalizat…
Low-depth quantum error correction via three-qubit gates in Rydberg atom arrays
Laura Pecorari, Sven Jandura, Guido Pupillo
Quantum error correction (QEC) requires the execution of deep quantum circuits with large numbers of physical qubits to protect information against errors. Designing protocols that…
Cavity polariton blockade for non-local entangling gates with trapped atoms
Vineesha Srivastava, Sven Jandura, Gavin K. Brennen +1
We propose a scheme for realizing multi-qubit entangled W-state and non-local and gates via a cavity polariton blockade mechanism with a system of atomic qubits coupled…
The iSWAP gate with polar molecules: Robustness criteria for entangling operations
Matteo Bergonzoni, Sven Jandura, Guido Pupillo
Ultracold polar molecules in optical lattices or tweezer arrays offer a promising platform for quantum information processing and simulation, thanks to their rich internal structur…

We consider stabilizer measurements for surface codes with neutral atoms and identify gate protocols that minimize logical error rates in the presence of a fundamental error source…
High-rate quantum LDPC codes for long-range-connected neutral atom registers
Laura Pecorari, Sven Jandura, Gavin K. Brennen +1
High-rate quantum error correcting (QEC) codes with moderate overheads in qubit number and control complexity are highly desirable for achieving fault-tolerant quantum computing. R…
Multi-qubit gates and Schrödinger cat states in an optical clock
Alec Cao, William J. Eckner, Theodor Lukin Yelin +8
Many-particle entanglement is a key resource for achieving the fundamental precision limits of a quantum sensor. Optical atomic clocks, the current state-of-the-art in frequency pr…
High-fidelity gates with mid-circuit erasure conversion in a metastable neutral atom qubit
Shuo Ma, Genyue Liu, Pai Peng +7
The development of scalable, high-fidelity qubits is a key challenge in quantum information science. Neutral atom qubits have progressed rapidly in recent years, demonstrating prog…

Sven Jandura, Vineesha Srivastava, Laura Pecorari +2
We present two protocols for implementing deterministic non-local multi-qubit quantum gates on qubits coupled to a common cavity mode. The protocols rely only on a classical drive…
Optimizing Rydberg Gates for Logical Qubit Performance
Sven Jandura, Jeff D Thompson, Guido Pupillo
Robust gate sequences are widely used to reduce the sensitivity of gate operations to experimental imperfections. Typically, the optimization minimizes the average gate error, howe…
