Mario Cartia from Agile Skill gives a presentation on quantum computing 101 for enterprises. He defines quantum computing as using quantum bits that can be in superpositions, unlike classical bits that are either 0 or 1. Some benefits include being able to solve problems too large for classical computers. While quantum computers won't replace classical ones, they may act as co-processors. Many areas could see disruption, but building useful applications requires overcoming technical challenges like developing computers with millions of qubits.

1. WHAT’S
QUANTUM COMPUTING?

1. WHAT’S
QUANTUM COMPUTING?
It’s a new model of computation different from
classical ones (like "Turing machine" or "Lambda
calculus") relying on the concept of qbit (quantum
bit) and using some peculiar phenomena of
quantum physics such as superpositions and
entanglement

A QBIT?

2. WHAT’S
A QBIT?
It’s the quantum version of the classical binary bit
but whereas in a classical system a bit would have
to be in one state or the other (0 | 1), quantum
mechanics allows the qubit to be in a coherent
superposition of both states/levels simultaneously

3. WHAT ARE
THE MAIN BENEFITS?
There are challenges that classical systems can’t
solve. For problems above a certain size and
complexity, we don’t have enough computational
power. Quantum computers leverage the quantum
mechanical phenomena to create states that scale
exponentially with number of qubits

4. WILL QUANTUM
COMPUTERS REPLACE
CLASSIC ONES?
No, there are problem classes for which it will make
more sense to use traditional CPUs. Think of
quantum processors as "co-processors" as, for
example, current GPUs

“QUANTUM SUPREMACY”
MEANS?

22. QUANTUM 101:

8. WHAT DOES
“QUANTUM SUPREMACY”
MEANS?
Quantum supremacy is the potential ability of
quantum computers to solve problems that
classical computers practically cannot
(in computational-complexity-theoretic terms)

8. WHAT DOES
“QUANTUM SUPREMACY”
MEANS?
Example:
Shor's algorithm is a quantum computer algorithm
for integer factorization which runs (theoretically)
in polynomial time instead of the exponential time
required by “classic” algorithms

9. DID GOOGLE REALLY
ACHIEVE QUANTUM
SUPREMACY?
Yes and No!
Google recently published a paper entitled
"Quantum supremacy using a programmable
superconducting processor" that proves to have
obtained it in a simple real-life use case

9. DID GOOGLE REALLY
ACHIEVE QUANTUM
SUPREMACY?
It is not possible to say today that we will soon be able
to apply quantum computing to the areas described in
the previous slides due to various hardware-related
technical difficulties not yet overcome as well as the
limited number of qbits available

10. HOW MANY QBITS
WOULD YOU NEED TO BUILD
RELEVANT APPLICATIONS?
Implementing real-world applications requires a
minimum of 1 million qbit(s). There are also other
relevant technical issues to be resolved such as error
correction. It's realistic to think of a 5-7 year time frame
to see the first real quantum applications on the market
