Consider the following statements with respect to Quantum Key Distribu...
- Quantum Key Distribution (QKD), also called Quantum Cryptography, is a mechanism to develop secure communication. It provides a way of distributing and sharing secret keys that are necessary for cryptographic protocols. Hence, statement 1 is correct.
- In the QKD, encryption keys are sent as ‘qubits’ (or quantum bits) in an optical fibre. Optical fibers are capable of transmitting more data over longer distances and faster than other mediums. It works on the principle of total internal Reflections. Hence, statement 2 is correct.
- In the QKD, the encryption is unbreakable and that’s mainly because of the way data is carried via the photon. A photon cannot be perfectly copied and any attempt to measure it will disturb it. This means that a person trying to intercept the data will leave a trace. Hence, statement 3 is not correct.

Consider the following statements with respect to Quantum Key Distribu...
Statement 1: QKD provides a way of distributing and sharing secret keys that are necessary for cryptographic protocols.
Statement 2: In QKD, encryption keys are sent as quantum bits in an optical fibre.
Statement 3: The encryption in QKD will be unbreakable because the data is carried by electrons and it cannot be perfectly copied.
Explanation:
QKD, or Quantum Key Distribution, is a method of secure communication that utilizes principles of quantum mechanics to distribute encryption keys between two parties. These keys are then used for cryptographic protocols to secure the communication between the parties.
Statement 1: QKD provides a way of distributing and sharing secret keys that are necessary for cryptographic protocols.
This statement is correct. QKD allows for the secure distribution of secret keys, which are essential for cryptographic protocols. By using quantum properties, such as the polarization of photons, QKD ensures that the keys exchanged between the parties remain secure.
Statement 2: In QKD, encryption keys are sent as quantum bits in an optical fibre.
This statement is correct. In QKD, the encryption keys are typically encoded as quantum bits, or qubits, and transmitted through an optical fiber. The qubits can be represented by the polarization states of photons, for example. The transmission of qubits ensures the security of the keys because any attempt to intercept or measure them would disrupt their quantum state, alerting the parties to potential eavesdropping.
Statement 3: The encryption in QKD will be unbreakable because the data is carried by electrons and it cannot be perfectly copied.
This statement is incorrect. In QKD, the encryption is not based on the fact that the data is carried by electrons, but rather on the principles of quantum mechanics. The security of QKD lies in the properties of quantum states and the detection of any interference or measurements performed on the transmitted qubits. While QKD provides a high level of security, it is not considered to be unbreakable in theory. However, any attempt to intercept or measure the qubits would introduce errors that can be detected by the communicating parties, alerting them to potential eavesdropping attempts.
Therefore, the correct statements are:
- Statement 1: QKD provides a way of distributing and sharing secret keys that are necessary for cryptographic protocols.
- Statement 2: In QKD, encryption keys are sent as quantum bits in an optical fibre.
Hence, the correct answer is option B.
Statement 2: In QKD, encryption keys are sent as quantum bits in an optical fibre.
Statement 3: The encryption in QKD will be unbreakable because the data is carried by electrons and it cannot be perfectly copied.
