Researchers Spy Finish Line in Race for Majorana Qubits
In 2010, JQI researchers proposed a method to create Majorana quasiparticles, which have been suggested as a desirable way to make qubits. Since then, researchers have been steadily exploring their idea, but practical demonstrations have proven elusive. Recent results from researchers at Microsoft have made JQI Fellow Sankar Das Sarma and JQI Co-Director Jay Sau optimistic that Majorana qubits are finally in sight. In a new paper, they analyzed the current technology and proposed an experiment to demonstrate Majorana qubits.
Scalable error correction strategies and the memory capacity of open quantum neural networks
Abstract: Due to the fragility of quantum states, quantum error correction is a necessary ingredient for scalable, beneficial quantum computation. In order not to lose the corrective power of an error correcting code, logical operations as well as the decoding need to be performed in a fault-tolerant way. In this context, I will present recent results on the modelling of lattice surgery for performing a logical state teleportation between surface codes, as well as recent experimental demonstration of fault-tolerant lattice surgery with quantum repetition codes [1].
