Quanta communication is a kind of when show benefit pesters effect to undertake information is delivered with quanta new-style communication means, it is the new research field of the quantum theory and union of information theory photograph.
The near future has allege from media article " existing quanta adds secret technology likelihood the blemish with earthshaking under cover " , cause public opinion heat to discuss. The dependability problem with quanta communication confidential safety makes topic central point, have oppugning quanta not less to correspond from media article is " pseudoscience " , be " fraud " .
Should introduce university of traffic of a Shanghai from media article Jin Xianmin group is collected at beforehand the printed books website, paper positive result that has not publish formally.
Say in article: "Shanghai traffic university studies group close is after the experimentation with constant course and attempt, discovered existing quanta adds secret technology likelihood the blemish with earthshaking under cover, breach this the strongest add close aegis not to need sharp weapon of what god arms however, use however ' aegis ' the physical blemish that itself exists. This studies this brings about the likelihood quanta to add close from originally in impression firm cannot defeat, turn and become can't bear flimsily. ...
Be applied extensively in the QKD(Quantum Key Distribution in quanta communication at present, quanta close key is distributed) the method is not perfect, study the group passes the accent of photon infuse laser that will have different seed frequency to change the method of laser frequency, observe the trends of the semiconductor laser of infuse photon then, obtain the information purloin that is as high as 60% finally to be led successfully unexpectedly. Obtain the information purloin that is as high as 60% finally to be led successfully unexpectedly..
On March 13 before dawn, jin Xianmin releases statement quickly to clarify, this job is not the security that negative quanta close key issues, rather, want to increase taller contrast smooth isolator to be able to solve this flaw in source end only, assure the security that quanta close key issues thereby.
Jin Xianmin expresses, there is a few in the report not quite accurate the part with development. His article is in theoretic the attack program that offerred a kind to distribute effective system source to carry physical flaw in the light of quanta close key, pass experimental data test and verify feasible. This job reminds and emphasize, for higher security, the light of the tall contrast that actual quanta close key distributes the source in the system to carry is kept apart not only indispensable, and want very big. In current effective system, some illuminant had adopted the smooth segregation of tall contrast, but some illuminant are returned.
"Our job does not deny quanta close key to issue theoretic absolutely security, adding because of quanta instead close provided theoretic absolutely security, make what the mankind pursued a few chiliad absolutely safe communication comes true nearly finally. And the our ceaseless physics that is aimed at effective system is safe the research of flaw problem is for this absolutely security becomes more reliable. Attack, it is to make quanta password more safe, impeccable. " Jin Xianmin is written.
10 days, on the press conference that in countrywide the Chinese People's Political Consultative Conference 13 2 second conferences hold, pan Jianwei of academician of standing vice-president, Chinese Academy of Sciences also responds to university of science and technology of committee member of countrywide the Chinese People's Political Consultative Conference, China say, the public has doubt to quanta communication technology, because quanta is mechanical,basically be the experience of life with them has very big different, even if be an egghead, the advanced theory that corresponds to quanta will surely not understand well. The scientific sex that so the public just can correspond to quanta generates suspicion, fear this technology is immature.
Pan Jianwei further explanation says, innovation achievement arrives to apply extensively from generation, connect regular meeting to pass 3 level. In the first phase, public bring into contact with brand-new the thing of the domain, most initial reaction is normally: Do not rely on chart. For instance the earliest camera, everybody feels soul is sucked went inside camera, dare use not quite. So inchoate quanta corresponds, somebody considers as pseudoscience, after when it development matures quite, feel this technology still does not have wide application again, have doubt. "We have the achievement of sex of a lot of innovation to had taken alive group forward position really now, we should have self-confidence. We should have self-confidence..
Nevertheless, pan Jianwei also expresses, current, among the process that quanta corresponds to be in the 2nd phase to be changed to the 3rd phase, need does much popular science work. "After when quanta communication is applied extensively, everybody feels it doesn't matter is curious, innovation process also was finished. Innovation process also was finished..
Physicist Pan Jianwei is called in China " the father of quanta " , his achievement before this by " the fighter that make a holiday " square boatman is oppugned in public frequently critically, latter even still sending rich to weigh Pan Jianwei for a time is not " the father of quanta " , however " the male relative of a senior generation that puts quanta satellite " .
Square boatman basically oppugns Pan Jianwei's quanta to add close communication to have exaggerated suspicion, and be the experiment of crave for greatness and success, latter of an ancient form of acupuncture becomes on social status 100 million yuan by this " science stars " . He expresses, be bungled gigantic endowment exploration quanta communication is equal to Bai Hua money.
And writer of famous popular science, " the current situation of time " author Wang Jize points out, oneself come in square boatman for years dozen of assiduous holiday is medium, however more and more the dependability that sees Pan Jianwei teachs scholarship.
In addition, on March 20, inc. of technology of quanta of aegis of division big country (abbreviation " quanta of aegis of division big country " ) more announce the provider distributes a product with quanta close key, furnish arena, successful filch arrives the person study beat a drum of quanta close key bear the palm 1 million yuan of RMBs.
According to introducing, during arena is held, the organization just will update titbits of mobile progress, activity in real time through the network, invite a nation the quanta expert of aegis quanta, safe expert and international standard expert, do work of a few popular science, popularize close key of communication of quanta technology, quanta, quanta to distribute, quanta " hacker " the knowledge that waits for each respects.
