      \tFrequency DomainQuantum Photonics

      Entanglement is a key resource for quantum information processing. Due to their robustness and unique capability for transmission over long distances, photons have proven to be an indispensable tool for investigation of entanglement and its applications. Discrete frequency bin entanglement \u2013 and encoding of quantum information in the frequency domain \u2013 is emerging as an active new research area. This form of photon entanglement offers potential both for practical advantages, e.g., compatibility with on-chip generation and fiber transmission, and for more fundamental ones, particularly generation of entangled states with high dimensionality (qudits rather than qubits). In this talk I discuss recent advances in manipulation and measurement of quantum states encoded and entangled in the photonic frequency degree of freedom or hyperentangled in time and frequency degrees of freedom. Although the perspective is primarily experimental, I will also attempt to provide examples of questions and challenges that connect to near-term quantum information.

      \tQuantum ChannelCapacities

      \tIn 1948, Shannon defined the notion of the capacity of a communicationchannel, and gave a formula for it. His paper essentially founded thefield of information theory, and channel capacity is central in thetheory and practice of information transmission. However, Shannon'sformula does not apply to channels in which quantum effects areimportant. If the channel, the transmitter, and the receiver can alluse quantum mechanics, we need a different formula. In fact, it turnsout that there are several formulas for the capacity of a quantumchannel, depending on whether you want to transmit classicalinformation or quantum information, and which additional resources(e.g. feedback or entanglement) the receiver and sender are allowed touse. The lecturediscusses these capacities of a quantum channel, focussingon the basics, but also mentionssome recent developments.
