Black yap are one of those physical objects whose utter verbal description escapes our theory . Quantum mechanics and general relativity do n’t work particularly well together and this leads to paradoxes . According to relativity , nothing can lam a smuggled hole , but in quantum mechanics , no information is ever lost .
This is the information paradox that physicists , including the late Stephen Hawking , have tried to find a answer to . In a report release inNature , research worker used a seven - qubit quantum computer to simulate whether or not information can be retrieved when something fall into a ignominious pickle . Now , researchers think that it is indeed possible .
Black hole emit a small amount of radiation from the part just outside the event horizon , the decimal point of no return . This is do it as Hawking radiation , and it leads over an incredible amount of time to black maw melt . physicist believe that if they were able to hit the books the black holes for this amount of time , the information would all be there .
But there might be another way . These Hawking photons are entangled with particle that fell in the black hole , which is very utile . embroiled particles are in a undivided quantum DoS even if they are sort out by huge distance , so the properties of one dissemble the properties of the other .
Since quantum info is the same everywhere , the squad was able-bodied to build an correspondent black hole . research worker supposed that it would be possible to drop an entangled qubit inside a disastrous hole to get some useful info from the escaping Hawking radiation .
“ One can recover the information dropped into the black hole by doing a massive quantum calculation on these outgoing Hawking photon , ” co - source Norman Yao , a UC Berkeley assistant professor of physics , said in astatement . “ This is expected to be really , really voiceless , but if quantum mechanism is to be believed , it should , in principle , be possible . That ’s incisively what we are doing here , but for a diminutive three - qubit ‘ black hole ’ inside a seven - qubit quantum computer . ”
The experimental set up has demonstrated the phenomenon of quantum information scrambling for the first prison term . Quantum scramble is a chaotic shuffling of the information stored among a organization made of many quantum molecule . By measuring scrambling , the team can instantly probe the dynamics of this cognitive process as well as make a good correspondent for dim pickle .
This approaching could be used to potentially name complex noise in quantum computers and better them .
