SUMMARY:Quantum data compression
CLASS:PUBLIC
DESCRIPTION:IQC SEMINAR - ZAHRA KHANIAN\, TECHNICAL UNIVERSITY OF MUNICH\n\
 n200 University Ave W. Waterloo On Can QNC 1201\n\nIn the seminal 1948 pap
 er \"a mathematical theory of communication\"\,\nShannon introduced the co
 ncept of a classical source as a random\nvariable and established its opti
 mal compression rate\, given by\nShannon entropy. Nearly five decades late
 r\, Schumacher rigorously\ndefined the notion of a quantum source and its 
 compressibility.\nSchumacher's definition involved a quantum system and co
 rrelations\nwith a purifying reference system. In our work\, we build upon
 \nSchumacher's quantum source model\, extending it to the most general\nfo
 rm allowed by quantum mechanics. This extension involves considering\nthe 
 source and the reference in a mixed state\, along with the presence\nof ad
 ditional systems treated as side information. We address and\nsolve variou
 s problems posed by these modifications\, determining the\noptimal compres
 sion rates. While our work contributes significant\nprogress in quantum so
 urce compression\, we point out remaining open\nquestions that require fur
 ther exploration.
