High-Fidelity Controlled- Z Gate with Maximal Intermediate Leakage Operating at the Speed Limit in a Superconducting Quantum Processor
Victor Negîrneac,Victor Negîrneac,Hany Ali,Nandini Muthusubramanian,Francesco Battistel,R. Sagastizabal,Miguel S Moreira,Jorge Marques,Wouter Vlothuizen,Wouter Vlothuizen,Marc Beekman,Marc Beekman,Chris Zachariadis,Nadia Haider,Nadia Haider,Alessandro Bruno,Leonardo DiCarlo +16 more
TL;DR: The sudden variant (SNZ) of the net zero scheme realizing controlled-Z gates by flux control of transmon frequency is introduced, compatible with scalable schemes for quantum error correction and adaptable to generalized conditional-phase gates useful in intermediate-scale applications.

Logical-qubit operations in an error-detecting surface code
Jorge Marques,B. Varbanov,Miguel S Moreira,Hany Ali,Nandini Muthusubramanian,Christos Zachariadis,Francesco Battistel,Marc Beekman,Nadia Haider,Wouter Vlothuizen,Alessandro Bruno,Barbara M. Terhal,Leonardo DiCarlo +12 more
TL;DR: This work realizes a suite of logical operations on a distance-two logical qubit stabilized using repeated error detection cycles, and demonstrates process tomography of logical gates, using the notion of a logical Pauli transfer matrix.
Journal ArticleDOI
Deployed measurement-device independent quantum key distribution and Bell-state measurements coexisting with standard internet data and networking equipment
R. C. Berrevoets,T. Middelburg,R. F. L. Vermeulen,Luca Della Chiesa,Federico Broggi,Stefano Piciaccia,Rene Pluis,Prathwiraj Umesh,Jorge Marques,Wolfgang Tittel,Joshua A. Slater +10 more
TL;DR: In this paper , a Measurement-Device Independent Quantum Key Distribution (MDI-QKD) system, containing a Bell-State measurement node, over the same fiber connection as multiple standard Internet Protocol (IP) data networks, between three nearby cities in the Netherlands.
Journal ArticleDOI
All-Microwave Leakage Reduction Units for Quantum Error Correction with Superconducting Transmon Qubits.
Jorge Marques,Haleemur Ali,B. Varbanov,Matvey Finkel,H. M. Veen,S. Valles-Sanclemente,Nandini Muthusubramanian,Marc Beekman,Nadia Haider,Barbara M. Terhal,Leonardo DiCarlo +10 more
TL;DR: In this article , the authors extend the quantum-hardware-efficient, all-microwave leakage reduction unit (LRU) for transmons in a circuit QED architecture proposed by Battistel et al. This LRU effectively reduces leakage in the second and third-excited transmon states with up to 99% efficacy in 220 ns.
Journal ArticleDOI
Post-fabrication frequency trimming of coplanar-waveguide resonators in circuit QED quantum processors
S. Vall'es-Sanclemente,Matvey Finkel,Nandini Muthusubramanian,Marc Beekman,Haleemur Ali,Jorge Marques,Christoforos P. Zachariadis,H. M. Veen,Thijs Stavenga,Nadia Haider,Leonardo DiCarlo +10 more
TL;DR: In this article , the use of a set of airbridges to trim the frequency of microwave coplanar-waveguide (CPW) resonators post-fabrication is presented.
