Quantum Error Correction Conference
That way, measurements made on the final state of the qubits are guaranteed to reveal relationships between qubits without revealing their values. The relevant dynamical models for both closed and open quantum systems are presented, along with the main results on their controllability and stability. Suppose that the state of qubit 8 at time 5 has implications for the states of both qubit 8 and qubit 11 at time 6.

He has worked on quantum control theory for the past 15 years and is well known for his contributions to quantum error correction, in particular the development of decoherence-free subspaces. Rugango et al. Authors of selected papers will be invited to submit extended versions to a IARIA Journal Articles will be submitted to appropriate indexes. The First International Conference on Quantum Error Correction, hosted by the USC Center for Quantum Information Science & Technology (CQIST), will bring together a wide group of experts to discuss all

If an error is detected, the protocol can trace it back to its origin and correct it. Todd A.

Shor’s insight was that it’s possible to measure relationships between qubits without measuring the values stored by the qubits themselves. But we didn’t have constructive examples of getting here.
It may be possible to implement the researchers’ scheme without actually duplicating banks of qubits. Share Comment Leave a comment Quantum computers are largely theoretical devices that could perform some computations exponentially faster than conventional computers can. How much redundancy remains to be seen: Certainly, if each state of a computation required its own bank of qubits, the computer might become so complex as to offset the advantages So we’re hoping that will be the case for ours, too.” Stephen Bartlett, a physics professor at the University of Sydney who studies quantum computing, doesn’t find the additional qubits required
It is worth remarking that in the quantum control literature a wealth of methods for noise protection and dynamical error-correction are based on symmetrization techniques , , , , , . But, Harrow says, some redundancy in the hardware will probably be necessary to make the scheme efficient. Lidar,Todd A. Topics of interest include, in random order: fault tolerance and thresholds, pulse control methods (dynamical decoupling), hybrid methods, applications to cryptography, decoherence-free subspaces and noiseless subsystems, operator quantum error correction, advanced
So they could correct eight errors in a 64-qubit quantum computer, for instance, but not 10. Shor is also responsible for the theoretical result that put quantum computing on the map, an algorithm that would enable a quantum computer to factor large numbers exponentially faster than a Campagne-IbarcqS. Thought the subject is still mostly theoretical in nature, the conference will include talks surveying the latest experimental progress, and will seek to promote an interaction between theoreticians and experimentalists.
Using the stabilizer formalism we derive an explicit scheme, involving feedback and an additional constant Hamiltonian, to protect art (n-1)-qubit logical state encoded in n physical qubits. Check This Out Published by IARIA XPS Press Archived in the free access ThinkMindTM Digital Library Prints available at Curran Associates, Inc. This allows us to extend in a natural way the gossip consensus algorithm to the quantum setting and prove its convergence properties to symmetric states while preserving the expectation of permutation-invariant Since the measurement doesn’t reveal the state of any of the qubits, modification of a misaligned qubit could actually introduce an error where none existed previously.

The final state represents the result of the computation. It’s possible to determine whether the first and second qubit have the same value, and whether the second and third qubit have the same value, without determining what that value is. A simple error-correcting code could, for instance, instantiate a single qubit of data as three physical qubits.

Brun is an Associate Professor of Electrical Engineering, Physics and Computer Science at the University of Southern California. I will begin by touching on some historical points: initial work on QEC is actually more than 20 years old, and the landmark work of Kitaev in 1996 which established 2D If one of the qubits turns out to disagree with the other two, it can be reset to their value. http://johnlautner.net/quantum-error/quantum-error-correction-ppt.html Basic subjects as well as advanced theory and a survey of topics from cutting-edge research make this book invaluable both as a pedagogical introduction at the graduate level and as a
So one of the highlights of this construction is that they actually got that down a lot.” “People had all of these examples of codes that were pretty bad, limited by Those types of measurements, in a real system, can be very hard to do. That’s why it’s really desirable to reduce the number of qubits you have to measure at once.” Time embodied A quantum computation is a succession of states of quantum bits. In doing so, we reinterpret the classical algorithm and the average consensus task as a symmetrization problem with respect to the action of the permutation group.
Scalable quantum computers require a far-reaching theory of fault-tolerant quantum computation.
