چکیده

In quantum information theory, a basic question often presented is how efficiently can one transmit classical information over a quantum channel.[1, 2, 3] Because of the non-orthogonality of quantum states, the channel capacity is different from that of the classical channel discussed in [4, 5] . Recently, this question has attracted new attention due to the rapid progress in quantum information theory. In particular, a theorem is established that the maximum attainable rate of asymptotically error free transmission of classical information over a quantum channel is precisely the Holevo bound.[6, 7, 8, 11]

The capacity of the quantum multiple-access channel

We define classical–quantum multiway channels for transmission of classical information, after recent work by Allahverdyan and Saakian. Bounds on the capacity region are derived in a uniform way, which are analogous to the classically known ones, simply replacing Shannon entropy with von Neumann entropy. For the single receiver case (multiple access channel) the exact capacity region is determi...

Sequential, successive, and simultaneous decoders for entanglement-assisted classical communication

Bennett et al. showed that allowing shared entanglement between a sender and receiver before communication begins dramatically simplifies the theory of quantum channels, and these results suggest that it would be worthwhile to study other scenarios for entanglement-assisted classical communication. In this vein, the present paper makes several contributions to the theory of entanglement-assiste...

Capacity Theorems for Quantum Multiple Access Channels Part I: Classical-Quantum and Quantum-Quantum Capacity Regions

We consider quantum channels with two senders and one receiver. For an arbitrary such channel, we give multi-letter characterizations of two different two-dimensional capacity regions. The first region characterizes the rates at which it is possible for one sender to send classical information, while the other sends quantum information. The second region gives the rates at which each sender can...

Exponent for classical-quantum multiple access channel

Multiple-user information theory, or network information theory, was started by C. E. Shannon, the founder of Information Theory [1]. The only multiple-user channel in classical information theory whose single-letter capacity region is completely known, is the multiple access channel (MAC). MAC is a channel with a single output and two (or more) inputs. Its capacity region was determined by R. ...

Classical Capacity of Quantum Binary Adder Channels

We analyze the quantum binary adder channel, i.e. the quantum generalization of the classical, and well–studied, binary adder channel: in this model qubits rather than classical bits are transmitted. This of course is as special case of the general theory of quantum multiple access channels, and we may apply the established formulas for the capacity region to it. However, the binary adder chann...
