李傳鋒：放眼未來(lái) 不懈探索

量子信息科學(xué)，主要是由物理科學(xué)與信息科學(xué)等多個(gè)學(xué)科交叉融合在一起所形成的一門(mén)新興的科學(xué)技術(shù)領(lǐng)域�！‘�(dāng)前，量子信息科學(xué)領(lǐng)域的研究工作在國(guó)際上剛剛起步，我國(guó)在這一領(lǐng)域的研究工作與國(guó)際同步，并且在許多方面居于國(guó)際領(lǐng)先地位。

李傳鋒，1973年2月生于山東省萊蕪市，1990年進(jìn)入中國(guó)科學(xué)技術(shù)大學(xué)物理系讀本科與研究生，師從郭光燦院士，1999年博士畢業(yè)后留校任教�，F(xiàn)為中國(guó)科學(xué)技術(shù)大學(xué)光學(xué)與光學(xué)工程系和中科院量子信息重點(diǎn)實(shí)驗(yàn)室副教授。

他多年來(lái)以科研為追求、以事業(yè)為依托，常年奮戰(zhàn)在量子信息科學(xué)一線(xiàn)， 為我國(guó)量子科學(xué)的發(fā)展做出了應(yīng)有的貢獻(xiàn)。

李傳鋒主要從事量子光學(xué)、量子信息、低維固態(tài)量子系統(tǒng)等的理論與實(shí)驗(yàn)研究。李傳鋒在目前已在Nature子刊，Physical Review Letters, Physical Review 等發(fā)表SCI論文50余篇。論文被SCI總引用760余次，最高單篇引用160余次。H影響因子15。

他在多光子糾纏態(tài)的制備與應(yīng)用，量子糾纏與量子關(guān)聯(lián)在噪聲信道中的演化等研究方向取得諸多開(kāi)創(chuàng)性成果。目前正致力于搭建真正意義上的量子通信網(wǎng)絡(luò)。

攻堅(jiān)克難 首次發(fā)現(xiàn)量子關(guān)聯(lián)可以不被環(huán)境破壞

在量子信息科學(xué)發(fā)展的初期，人們認(rèn)識(shí)到糾纏是量子信息技術(shù)優(yōu)越性的關(guān)鍵所在。然而隨著近幾年的深入研究，人們發(fā)現(xiàn)了一個(gè)更普遍的概念—關(guān)聯(lián)，它反映了量子態(tài)各部分之間的相互聯(lián)系。關(guān)聯(lián)可分為經(jīng)典關(guān)聯(lián)和量子關(guān)聯(lián)，而糾纏只是量子關(guān)聯(lián)中特殊的一類(lèi)。人們發(fā)現(xiàn)，沒(méi)有糾纏的量子關(guān)聯(lián)也能實(shí)現(xiàn)許多量子信息過(guò)程，而且量子關(guān)聯(lián)可以用來(lái)解決諸如相變等物理難題。

但作為量子通信和量子計(jì)算領(lǐng)域重要資源的量子關(guān)聯(lián)非常脆弱，很容易被環(huán)境破壞而消失，如何解決這一問(wèn)題，一直是對(duì)學(xué)術(shù)界的極大挑戰(zhàn)。中國(guó)科大中科院量子信息重點(diǎn)實(shí)驗(yàn)室李傳鋒博士研究組，在光學(xué)系統(tǒng)中制備出各種貝爾對(duì)角態(tài)，用它們作為初始態(tài)在消相干環(huán)境中進(jìn)行傳輸，在實(shí)驗(yàn)上研究關(guān)聯(lián)的演化。他們?cè)谑澜缟鲜状伟l(fā)現(xiàn)了一類(lèi)初態(tài)，其量子關(guān)聯(lián)能在很大范圍的消相干環(huán)境中不被破壞，稱(chēng)之為量子關(guān)聯(lián)無(wú)消相干子空間。同時(shí)，他們還驗(yàn)證了量子關(guān)聯(lián)與經(jīng)典關(guān)聯(lián)在消相干演化過(guò)程中的突變現(xiàn)象，并證實(shí)，某些特殊的初始態(tài)在演化過(guò)程中量子關(guān)聯(lián)可以大于經(jīng)典關(guān)聯(lián)，推翻了以前文獻(xiàn)中經(jīng)典關(guān)聯(lián)一定大于等于量子關(guān)聯(lián)的猜想。這項(xiàng)成果將極大地推動(dòng)量子關(guān)聯(lián)的物理學(xué)研究及其應(yīng)用研究，尤其是量子關(guān)聯(lián)無(wú)消相干子空間和關(guān)聯(lián)演化中的突變現(xiàn)象，更是值得深入探索的重要科學(xué)問(wèn)題。

精益求精 解決對(duì)量子糾纏在噪聲信道中演化進(jìn)行有效刻劃的難題

量子信道是構(gòu)造量子網(wǎng)絡(luò)必不可少的物質(zhì)基礎(chǔ)，由于真實(shí)信道具有不可避免的損耗，因此如何在實(shí)驗(yàn)上有效地定量描述糾纏在信道中的傳輸，一直困擾著學(xué)術(shù)界。以往的方法是采取態(tài)層析技術(shù)，但由于各粒子間糾纏的存在，要對(duì)多粒子態(tài)進(jìn)行層析，需要的測(cè)量次數(shù)隨粒子數(shù)呈指數(shù)增長(zhǎng)，其難度難以想象。

李傳鋒研究組采用一種新的表征方式，他們應(yīng)用光學(xué)體系在實(shí)驗(yàn)上證實(shí)，只要給定輸入態(tài)的糾纏度便可輕而易舉地得到輸出態(tài)的糾纏度，這對(duì)于量子網(wǎng)絡(luò)通信具有重要意義。

再創(chuàng)輝煌 首次觀(guān)察到量子糾纏“死而復(fù)活”現(xiàn)象

隨著量子信息研究的不斷深入，糾纏態(tài)在信道中的傳輸過(guò)程越來(lái)越受到關(guān)注，因?yàn)檫@關(guān)系到在非局域的觀(guān)點(diǎn)下重新考慮以前的許多量子過(guò)程，并且是在量子信息的實(shí)用化過(guò)程中必須要考慮的問(wèn)題。

前人的理論工作表明，在噪聲環(huán)境中糾纏態(tài)的演化和單體系的演化很不相同，后者是指數(shù)衰減的，而前者存在糾纏的突然死亡。如果噪聲信道具有非馬爾科夫效應(yīng)，糾纏突然死亡后可以復(fù)活。這對(duì)量子存儲(chǔ)具有重要意義。

李傳鋒研究組創(chuàng)造性地利用特制的法布里-玻羅腔作為量子信道，在光學(xué)體系中首次觀(guān)測(cè)到量子糾纏的崩塌與復(fù)原現(xiàn)象，即糾纏逐漸減少后在相同環(huán)境下繼續(xù)傳輸又會(huì)自動(dòng)增加。特別有趣的是，他們還首次觀(guān)察到了量子糾纏突然死亡一段時(shí)間后又重新復(fù)活這一奇異現(xiàn)象。這一成果將在量子存儲(chǔ)等方面獲得重要應(yīng)用。
