DESCRIPTION:By: Poulami Das - Georgia Institute of Technology\nIC/SB Facul
 ty candidate\n\nAbstract\nQuantum computers can solve many important appli
 cations that are beyond the capabilities of conventional computers. Howeve
 r\, noisy quantum hardware leads to errors during program execution which 
 limit us from running applications with high fidelity. Quantum information
  can be protected by using quantum error correction\, but it requires huge
  resource overheads that are impractical on near-term systems with a few h
 undreds of qubits. These near-term systems can speed up certain domain-spe
 cific applications even in the presence of errors. Simultaneously\, they a
 re used to understand error correction at a small-scale to pave the pathwa
 y toward fault-tolerant systems that can unlock the full potential of quan
 tum computing.\n \nIn this talk\, I will provide an overview of my contri
 butions in the quantum software and architecture stack to improve the reli
 ability of quantum computers. I will introduce ANGEL\, a quantum compiler 
 that leverages application and device error characteristics to reduce the 
 impact of gate errors during program execution. ANGEL creates proxy circui
 ts that imitate a given application\, runs them on the device\, and builds
  an error profile which is then used to learn the optimal sequence of low-
 level gates to translate the program. Next\, I will describe the challenge
 s in enabling real-time quantum error correction within a budget of a few 
 micro-seconds and discuss LILLIPUT\, an efficient lookup table error decod
 er. LILLIPUT only stores entries corresponding to correctable errors and s
 ignificantly reduces the memory overheads of the lookup tables. I will als
 o briefly discuss the system-level organization required for quantum error
  correction at large scale. Finally\, I will conclude with my future resea
 rch vision towards building a unified software stack for quantum computing
 \, designing systems for enabling scalable quantum computers\, and archite
 cting cryogenic systems.\n\nBio\nPoulami Das is a PhD candidate at Georgia
