• Authors: Yuval Idan and Avihai Didi
• Abstract summary: In this project we examine several different quantum key distribution protocols which we divide into ones utilizing qubits whose Hilbert spaces are two dimensional. In the papers we'll examine are implemented using the orbital angular momentum of twisted photons. In section [7] we present a unified view of all the relevant data for the different protocols, and argue for the benefits and drawbacks of the different protocols for different applications.

• Abstract: In this project we examine several different quantum key distribution protocols which we divide into ones utilizing qubits whose Hilbert spaces are two dimensional and ones whose Hilbert space dimension is greater than two, these units of data in quantum computers are known as qudits and in the papers we'll examine are implemented using the orbital angular momentum of twisted photons. In sections [3] and [4] the specific procedures of each protocol are briefly described and followed by an examination of the theoretical and experimental merits of each protocol. These merits are measured in the bit error rate tolerance $e_b$, which quantifies the maximum channel noise and the key rate $R$ which quantifies the rate at which data is transferred in the protocol. In section [7] we present a unified view of all the relevant data for the different protocols, and argue for the benefits and drawbacks of the different protocols for different applications.

• Separable Power of Classical and Quantum Learning Protocols Through the Lens of No-Free-Lunch Theorem [70.42372213666553]
  The No-Free-Lunch (NFL) theorem quantifies problem- and data-independent generalization errors regardless of the optimization process. We categorize a diverse array of quantum learning algorithms into three learning protocols designed for learning quantum dynamics under a specified observable. Our derived NFL theorems demonstrate quadratic reductions in sample complexity across CLC-LPs, ReQu-LPs, and Qu-LPs. We attribute this performance discrepancy to the unique capacity of quantum-related learning protocols to indirectly utilize information concerning the global phases of non-orthogonal quantum states.

  Quantum key distribution (QKD) allows the establishment of common cryptographic keys among distant parties. Recently, a QKD protocol that circumvents the need for monitoring signal disturbance, has been proposed and demonstrated in initial experiments. We derive the security proofs of the round-robin differential phase-time-shifting protocol in the collective attack scenario. Our results show that the RRDPTS protocol can achieve higher secret key rate in comparison with the RRDPS, in the condition of high quantum bit error rate.
