In the quest for universal, fault-tolerant quantum computation, #UQ's CHSR's Riddhi Gupta and co-authors demonstrate a proof of concept, crucial piece of error correction published in Nature. bit.ly/3HfrJYx

Take a look at a blog post about new research led by Guanyu Zhu where we investigate universal quantum computing using transversal logic gates with LDPC color codes

PRX Quantum Ben Brown Julio I am happy about this work, not the least because it transfers ideas of #anyon condensation to the context of #quantumerrorcorrection. And because it allows to think of new #Floquetcodes.

You can learn about our new work on YouTube in a Qiskit Paper Review youtube.com/watch?v=N4wzAh… with me and my IBM Research colleagues Andrew Cross, Maika Takita and Olivia Lanes, where we talk about our magic state preparation experiment, and about IBM QEC research more broadly.

Now that's a magic result: A new error-suppressing encoding circuit prepares high-fidelity “magic states”, which could play an important role in fault-tolerant quantum computing. ow.ly/ekvH50RZZOC

Our work demonstrating the preparation of high-fidelity encoded magic states, led by Riddhi Gupta, was recently written up in Physics World.

Enthusiastic to work on a team that is solving the theoretical challenges that will help us build a quantum computer? The quantum computing theory team at IBM are looking for interns to work with us in Summer 2025 careers.ibm.com/job/21084509/q… Please be in touch with any questions!

Major update to our "Low-overhead magic state distillation with color codes"! We present optimised MSD protocols for color codes. Notably, magic state cultivation is now integrated in our scheme! w/ Felix Thomsen, Nick, Ben Brown, Stephen Bartlett arxiv.org/abs/2409.07707

Dynamical codes for hardware with noisy readouts We deliver good design choices for measurement schedules for dynamical codes in #quantumerrorcorrection in the presence of noisy measurements. And define the "teraquop volume" as a new metric. arxiv.org/abs/2505.07658 In detail,
