HTTP:: Six Photons Make For a Better Qubit
--------
According to a new research conducted by Swedish and Polish experts, photons used for quantum-data transmissions have strength in numbers. They reveal that the elementary particles, which make up quantum bits, or qubits, the basic units of a quantum computer, are much less likely to trigger the scrambling of transmitted quantum data if they work in groups of six. The methods currently used for sending and storing quantum data are extremely fragile at this point, which is one of the main reasons why endeavors to build a quantum computer of efficient quantum networks have been plagued with failure, ScienceDaily reports. In “classic” computers, a bit is stored in one of two states, either “1” or “0.” Its value is set by convention, so that engineers can go on with constantly building increasingly advanced processors and microchips. However, photons are very different from this setup. Because they are quantum mechanical objects, they can exist in a number of stat!
es at the same time, which would roughly translate into “1,” “0” and “1 and 0” at the same time. Also, they can be entangled, a process that results in the newly formed structure holding precisely on bits of information. Up until now, the frailty of qubits has been the main obstacle in ...
