‘‘And then one day I walked down the street and I realized that I felt like a minority. I felt like I was an English-speaking part of a group of Montreal and Quebec and that I was actually a minority. And it was the strangest feeling to be inside Canada that’s English, but inside Quebec that’s French. Inside Montreal or this area in English, and still be a minority inside of a majority.’’ (QEC/...

Fault-tolerant quantum error correction (QEC) is crucial for unlocking the true power of computers. QEC codes use multiple physical qubits to encode a logical qubit, which protected against errors at qubit level. Here we trapped ion system experimentally prepare $m$-qubit GHZ states and sample measurement results construct $m\times m$ $[[m^2,1,m]]$ Shor code, up $m=7$. The synthetic fidelity sh...

If a quantum computer is stabilized by fault-tolerant quantum error correction (QEC), then most of its resources (qubits and operations) are dedicated to the extraction of error information. Analysis of this process leads to a set of central requirements for candidate computing devices, in addition to the basic ones of stable qubits and controllable gates and measurements. The logical structure...

BACKGROUND Assessment of the level of exposure to work-related musculoskeletal disorders (WMSDs) risk factors can be an appropriate basis for planning and implementing an interventional ergonomics program in the workplace. This study was conducted among workers of an Iranian sugar-producing factory to determine WMSD prevalence rate among production workers and to assess the level of exposure to...

Quantum Error Correction (QEC) is an important technique for protecting quantum information against decoherence and errors. This involves the design implementation of algorithms techniques to minimize error rates increase stability circuits. One key parameters in QEC distance error- correcting code, which determines number errors that can be corrected. Another parameter probability, quantifies ...
