Quantum error correction is a key component of fault-tolerant #quantum computation as it counteracts noise. But QEC itself is susceptible to the effects of device imperfections and fluctuations. Discover how Nord Quantique is using quantum control to achieve an overall error reduction by employing Boulder Opal’s closed-loop optimization engine.

ELQ: ENTANGLED LOGICAL QUBITS https://lnkd.in/e4W-nXg8 The Entangled Logical Qubits (ELQ) program aims to advance the state of the science in universal fault-tolerant quantum computing (UFTQC) by demonstrating high-fidelity entanglement between error-corrected logical qubits using a modular architecture. This is an essential step towards the realization of UFTQC and its potential to greatly outperform classical computing in solving certain classes of problems, including those of interest to the Intelligence Community (IC), and to the U.S. Government as a whole.

#InfiNETInternetBrowser #DNAQubits - Infinite 8 integrates its new Locked DNA Qubits into the InfiNET Internet Browser for Web searches. Infinite 8 claims the Locked DNA Qubit search is more secure than any other Browser search, and faster on low-power devices. Now, the Browser creates 50 random frequencies, each with 1000 decimal places after the digit, which are each required to be perfect to the last decimal for every search confirmation. "The use of quantum entanglement, teleportation, and frequency mechanics will bring incremental improvements to many areas of the Universal Online Digital Experience, and today's example show practical application and implementation of Hybrid Quantum and Quantum technologies." - Ean Mikale, JD, Principal Engineer/Founder, Infinite 8 Industries, Inc. The application is the first commercial implementation of Locked DNA Qubits in Production. #Infinite8 #ComingSoon #Q1 #HybridQuantum #Supremacy | https://lnkd.in/gRzfxqkB

In case you missed the QuEra webinar for their error-corrected quantum computing roadmap, it is up on their website now. Here it is. A few lingering questions that I had: 1. What is the residual error rate (logical error rate) after error correction at each stage of the roadmap. This may presume what the starting physical error rate is at each stage of the roadmap, so it would be helpful to see that too as well as the "nines" of error rate improvement expected at each stage. 2. Count of physical qubits per logical qubit at each stage. You can sort of estimate this, but not exactly - it would be better to have it explicit. 3. Estimated maximum circuit size - gate count - at each stage of the roadmap. How much can people really do. 4. And of course, my own preferred metric, estimate of width of quantum Fourier transform and quantum phase estimation which can be performed at each stage of the roadmap. They should have had a little tombstone in the corner - "RIP Jack's 48 qubit-processor" - which was so prominently featured in the PR, but is now gone! They focus on 10, 30, and 100 logical qubits, none appearing to use the [8,3,2] code that their 48 logical qubit processor demonstration used. #QuEra #QuEraComputing #LogicalQuantumProcessor #NeutralAtomQubits #QuantumComputing #QuantumApplications #QuantumAlgorithms #QuantumInformationScience #QIS #QuantumTechnologies #QuantumTech #Quantum https://lnkd.in/eXbnDfrz

#qecarxiv Towards early fault tolerance on a 2×N array of qubits equipped with shuttling [https://lnkd.in/eUm23aFA] Explores the potential of lower-dimensional structures for achieving fault-tolerant quantum computing. The authors focus on a 2×N array of qubits, where interactions between non-neighboring qubits are enabled by shuttling logical information along the rows of the array. Despite the constraints of this setup, the paper demonstrates that error correction is possible and identifies classes of codes suited to this platform1. Using silicon spin qubits as a practical example, the authors provide a protocol for achieving full universal quantum computation with the surface code. Numerical simulations show that both surface code and more complex qLDPC codes efficiently suppress gate and shuttling noise, allowing for the execution of quantum algorithms within the classically intractable regime1. This work brings us closer to executing quantum algorithms that outperform classical machines. The shuttling noise threshold seems low, however.
