IBM Shows First Full Error Detection for Quantum Computers By Jeremy Hsu Posted 29 Apr 2015 | 10:00 GMT Photo: IBM Research Quantum computersmustovercome the challenge of db2 sqlstate detecting and correcting quantum errors before they canfulfill their promise ofsifting through sql codes pdf millions of possible solutions much faster than classical computers. “With our recent four-qubit network, we built a system that jcl abend codes allows us to detect both types of quantum errors,” says Jerry Chow, manager of experimental quantum computingatIBM’s Thomas J. Watson Research Center, in Yorktown Heights, N.Y. Chow, who, along with his http://www.ibm.com/support/knowledgecenter/SSEPEK_11.0.0/codes/src/tpc/db2z_n.html IBM colleaguesdetailed their experiments in the 29 April issue of the journalNature Communications, says,“This is the first demonstration of a system that has the ability to detect both bit-flip errors and phase errors”that exist in quantum computing systems. The IBM system consists of four quantum bits, or qubits, arranged in a 2-by-2 configuration on achip measuring about 1.6 square centimeters (0.25square inch). http://spectrum.ieee.org/tech-talk/computing/hardware/ibm-shows-first-full-error-detection-for-quantum-computers Each qubit is roughly the equivalentof a bit ofinformation that, in classical computing, can represent values of either 1 or 0. Like classical bits, qubits can experience “bit-fliperrors” that switch the values around.But qubits are also vulnerable to a different type of error called a “phase error,” because they take advantage of the quantum physics phenomenon called superpositionthat allows them totemporarily exist as both1 and 0 simultaneously. A phase error can change the superposition“sign” of the phase relationship between the 0 and 1 values. Detecting quantum errors is anything but straightforward. Classical computers can detect and correct their bit-flip errors by simply copying the same bit many times and taking the correct value from the majority of error-free bits. By comparison, the fragility of quantum states in qubits means that trying to directly copy them can have the counterproductive effect of changingthe quantum state. Researchers get around that problem by relyingonentanglement, the quantum physics phenomenon that allows a qubit to share its quantum state with many other qubits through a quantum connection. In this case, IBM built its four-qubitgrid architecture to exploitthe information shared betwe
