Fault-Tolerant Logical Operations and Efficient State Preparation in Modular Quantum Architectures with Noisy Interfaces
Siddardha Chelluri, S. Siddardha Chelluri, Riccardo Mengoni +4
Modular quantum computing is a leading paradigm for scaling quantum computation beyond the resource limitations of monolithic devices. In this architecture, multiple quantum proces…
Shallow-depth GHZ state generation on NISQ devices
S. Siddardha Chelluri, Stephan Schuster, Sumeet +1
In this work, we focus on GHZ state generation under the practical constraint of limited qubit connectivity, a hallmark of current NISQ hardware. We study the GHZ state preparation…
Bosonic quantum error correction with microwave cavities for quantum repeaters
S. Siddardha Chelluri, Sanchar Sharma, Frank Schmidt +2
Long-distance quantum communication necessitates the use of quantum repeaters, which typically include highly coherent quantum memories. We provide a theoretical analysis of the se…
A resource- and computationally-efficient protocol for multipartite entanglement distribution in Bell-pair networks
S. Siddardha Chelluri, Sumeet Khatri, Peter van Loock
Multipartite entangled states, such as Greenberger--Horne--Zeilinger (GHZ) states, are important resources in multiparty quantum networking tasks. We consider protocols for generat…
