Fault-Tolerant Logical Operations and Efficient State Preparation in Modular Quantum Architectures with Noisy Interfaces
Siddardha Chelluri, Riccardo Mengoni, Tom Darras +3
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…
