\u00a0<\/span><\/p>\nThe photons move through the channels, with many channel splitters. These \u2018switches\u2019 can be geared from the outside, by local heating. By doing so, a photon can be sent from one mode to another, but also somewhere in between, following the typical quantum phenomenon of superposition.<\/p>\n
The advantage of this processor is that it works at room temperature, as well as the photons. The advantage is that the photon \u2018quantum bits\u2019 are more robust and less noisy than superconducting qubits. Measurements at the 12 outputs shows what has happened in all channels along the way.<\/p>\n
Thus, due to the superior photon source and larger quantum processor, Van der Meer was able to conduct multiple experiment, including one about the retention of information.<\/p>\n
How will this further scientific knowledge?<\/h3>\n
Quantum mechanics is a theory that stays constant in terms of information: through time, two systems will not look more similar. Thermodynamics, however, is a theory losing information: two systems will, in time, look more and more similar. This means that, typically, quantum mechanics and thermodynamics cannot be true at the same time.<\/p>\n
However<\/span>, a system that shows quantum <\/span>mechanic<\/span> behaviour <\/span>as a whole<\/span> can<\/span> have thermodynamic subsystems. So, there must be a way for information to escape within the larger system.<\/span><\/p>\nTherefore, further development of the photonic quantum processor will be conducted by a UT spinoff company called Quix Quantum. This company already sold a number of processors to research groups in the world, which it aids them in gaining experience with conducting experiments with this novel quantum processor.<\/p>\n","protected":false},"excerpt":{"rendered":"
A research team from the University of Twente have developed a quantum processor working with light and photons. What makes this quantum processor \u2018better\u2019? The latest version not only has more inputs and outputs, but it can also be fed by a photon source that is able to produce identical photons. This means that physical […]<\/p>\n","protected":false},"author":21,"featured_media":19083,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"footnotes":""},"categories":[24615],"tags":[821,17008],"acf":[],"yoast_head":"\n
