"Developments in superconducting erasure qubits
for hardware-efficient quantum error correction"

Abstract:

Quantum computers are inherently noisy, and one of the key challenges for achieving large-scale, fault-tolerant quantum computing is to implement quantum error correction. In recent years, significant progress has been made in exploring and developing quantum error correction theory, in addition to experimental demonstrators of important milestones using various hardware platforms. An interesting direction has gained popularity of designing hardware that has a specific noise profile, leading to a significantly higher threshold for noise with certain quantum error correcting codes. In this talk, I introduce erasure qubits, which enable a particular type of hardware-efficient quantum error correction that uses a "dual-rail encoding" concatenated with another code. I will discuss implementations of erasure qubits using superconducting hardware, giving an overview of recent developments in theory and simulation, and hardware demonstrators. I will also cover the differences between implementations; near-term applications to the NISQ era and quantum error detection; and challenges and open questions for this approach.



BIO:
Maria Violaris works at Oxford Quantum Circuits doing quantum computing research and advocacy. She recently completed her PhD in quantum information at the University of Oxford, and is a prize-winning science communicator. Additionally she hosts a Quantum Foundations Podcast and other videos about quantum science on her YouTube channel. Alongside her PhD, she worked with IBM Quantum to create a 14-part video series for the Qiskit YouTube channel, using quantum computers to demystify paradoxes. Previously she interned at Riverlane, where she built a “Raspberry Pi quantum computing lab” simulation. She writes quantum news articles for Physics World; is on the IOP QQQ group committee; and founded Oxford Quantum Information Society. She frequently creates and participates in events, initiatives, talks and workshops aimed at High School students, public and learners, and has published research in quantum education. 


The meeting is organized by the Quantum AI Foundation and QPoland.
