The symposium aimed to give an overview of the research area of quantum computing, as seen from physics, mathematics and computer science.
Quantum computing is often seen as a threat to Bitcoin ...
Could people theoretically break Bitcoin using quantum computing methods?
In short the answer is No , but Quantum computing will likely bring some issues that will need to be addressed sooner than we think.
I had the chance to chat with David El Kouss on the latest developments in the Quantum Computing and the possible threats posed on Elliptic Curve Cryptography System used to sign bitcoin transactions , and on the Hashing Algorithm which constitutes the core strength of Bitcoin protocol.
In theory The security of Elliptic Curve Cryptography systems could be jeopardized due to the fact that a Quantum Computer could deduce the private key of an address if it knows the public key.
In addition Quantum computing could be used to reduce the difficulty of hashing , by reducing the number of bits needed for computations. In fact that a qubit can assume a state of both zero and one at the same time.
As Quantum computing is one step closer to becoming a reality, there are challenges down the road. Whether it is in science or engineering , there are scientific questions that need to be answered first.
Concerns related to the material , design , and the time consuming tuning - In addition to control electronics , engineering of voltage pulses , and microwave bursts on each qubit , these all hinder scaling up and require professional engineers to complement the science.
Here Qutech stepped up as the new collaboration between Delft University for Technology , and TNO funded by Intel with $15 million per year. It combines 5 engineering faculty , 5 physics facility , 20 senior scientists , 20 technicians , 10 administratieve staff , nanofab facilities and equipment , in order to deliver the first Quantum Internet within the next 5 -10 years.

The Quantum Internet , Qutech is aiming for is an optically-connected network of (small) quantum processors. The network will be capable of sending and receiving quantum information.
The Quantum Internet has two main applications.
The first is providing a fundamentally secure way of communicating in which security is guaranteed by the laws of physics.
The second application is connecting quantum computers, both to other quantum computers for exponential speedup and to remote users/providers for secure quantum computing “in the cloud” , and to send information in a completely secure way by means of teleportation
Until quantum computing to be introduced gradually, questions like is the Quantum Internet a friend or a foe are open to discussion.
