This document discusses quantum computing applications in the financial sector. It describes how quantum computers work using qubits that can be in multiple states at once, allowing for greater processing power. Examples of applications include improving traffic management through quantum machine learning, predicting crimes using social media analysis, and addressing the COVID pandemic through computational chemistry. Major companies developing quantum computing include Microsoft, Google, which has achieved quantum supremacy. The document also discusses how quantum cryptography can enhance banking security through quantum key distribution and the ability to detect any third party interference.

2. What Are Quantum Computers
• How Classical computers work
It deals in bits i.e. 0 and 1
• How a Quantum Computer works
It deals with qubits i.e. it can be in both the states 0 and 1 ( name
of this phenomenon is Superposition)

5. Quantum Cryptography
 Quantum cryptography is the science of exploiting quantum mechanical properties to
perform cryptographic tasks.
 The most well known and developed application of quantum cryptography is Quantum Key
distribution (QKD).
 An important and unique property of quantum key distribution is the ability of the two
communicating users to detect the presence of any third party trying to gain knowledge of the
key. (Explained in Slide no.7 and 8).
 Entanglement based protocols
The quantum states of two (or more) separate objects can become linked together in such a
way that they must be described by a combined quantum state, not as individual objects. This is
known as entanglement and means that, for example, performing a measurement on one object
affects the other. If an entangled pair of objects is shared between two parties, anyone
intercepting either object alters the overall system, revealing the presence of the third party
(and the amount of information they have gained).

9. Medical use case to address recent CORONA Pandemic
• "In the field of computational chemistry, high accuracy
property prediction is considered to be very difficult.
Running quantum computing methods with Quantum
optimization solutions, we are getting results that are more
accurate than other algorithms."

11. Characteristics of quantum cryptography
-The concept of Quantum Cryptography was introduced by Bennett
and Brassard in 1984.
Classical cryptography:
• M=P*Q (Difficult to find P and Q when we know
both are prime numbers and value of M.)
• ABHAS =128119
• 128119 * 143 = 18,321,017 (This is the
cryptographic message but it has to be
converted to binary when it is made to read by
classical computers in the form of binary, 0 and
1).
• Even the best of the classical computer has
limitation in prime number. (Largest prime
number = 2^74207281 -1)
Quantum Cryptograpgy:
• In QC information is transferred in as
photon polarization. (Directions are
0,1,-,+ i.e. vertical and horizontal
and two diagonals)
• Polarization detectors translate
photons to bits if it is passed.
• It is p assed through the filter
because of the position of the
photon.
• Receiver then reaches out to the
sender for which detector he used for
photon.
• After confirmation then the quantum
key is found and used to decrypt

12. How the traditional encryption system works
Monday, April 10, 2023
For traditional secure transaction
Below 3 steps are followed:
Encryption (It is developed in
software using specific patterns.)
The Exchange (Eavesdropping can
be done just like the diagram.)
Encryption Algorithm (to decode the
encryption so as to get the data.)
e.g. Payroll company

13. How Quantum cryptography is enhancing the
process
In Quantum cryptography comes up with the following solutions:
 Random Number Generator (For
encryption)
 Quantum Key Distributor ( If also any
eavesdrop happens in the middle , then
Both the parties are alerted.)
