Institute for Quantum Computing – Pushing Computational Limits


Harnessing the laws of nature related to
quantum mechanics, understanding them, controlling them and develop technologies in new applications.
This is what is behind the Institute of quantum
computing. We first started in 2002 with a few rooms in the physics
and the math building but then suddenly, as the Institute grew, we needed something which was better, more technical for the different types of experiments we
would do and also to really bring the different people of the University together.
It has grown to about 20 faculties, 40 Postdocs, a little bit
more than 100 students 20-30 staff, 200 researchers and staff that are really pushing the limit of
quantum science. Quantum mechanic’s is a theory really
originally developed to describe atoms and molecules and very small things
like that and there are certain aspects of the way it says atoms and molecules
behave that are kind of weird from from our macroscopic or our big point of view.
You might be able, at least theoretically to use this weirdness to
make a new class of computers that’s really kind of, that’s really
exponentially more powerful than the computers that exist today. So our superconducting circuits that we
work with we operate them at very, very low
temperatures so typically we work at 20 millikelvin, which means 20,000ths of
a degree above absolute zero. At the very low temperatures we can
actually make these or engineer these circuits so that they behave quantum
mechanically. There’s also been a lot of interest that’s developed in the last say five years around what’s
called quantum simulation. So, using quantum computers to simulate
quantum systems say like molecules so they could be
used for drug design, for finding new molecules for drugs, or for
designing new materials in a kind of calculated ways. Quantum
material refers to the material that can be used for either quantum information or can be used to tackle certain quantum mechanical problems. What we aim to do here is to combine the
these materials with different properties and take advantage
of all of them, put them together and create a device
that is capable to manipulate the information in a
quantum mechanical way. Our system has 7 modules. All of these modules are connected through our out hi vacuum for the material to be prepared in 1 chamber
can be transferred into the next chamber without any contaminations. This
way we get the better material and the best interface. The understanding of
quantum materials is not only important for developing the machine, the quantum computer itself. It also advanced our understanding of the technology itself.Trying to develop quantum computers there’s all kinds of different techniques essentially using all the
magic of quantum systems and quantum cryptography is a spin-off
of this where you can use the same sort of weird quantum properties to actually establish a secure key between two different parties. We have more or
less the technology to start commercialization in fact there are already
companies selling devices along these lines and what my research here in particular is working with is trying to improve
whether these devices that people are claiming or selling whether the
research groups are companies actually ours as secure as their proofs claim. Quantum cryptography is very important in even in present day at
the moment because it is a commercial technology
its allowing people already to start using this physical security layer to things that they want to share
securely between different parties. Quantum communication which is about exchanging quantum signals between
individual communication partners. When it’s done at the moment it’s
limited in distance to about 100km by mostly optical fiber or also free
space links on the ground and of course global distances are way
larger, right? We are talking thousands of
kilometers. We know that with today’s technology
so todays satellite technology it’s possible to get a quantum signal
from ground to a satellite in space and exchange a key over, over that distance and then
using the information that is that was generated on the satellite
to effectively connect any two sites on the ground so effective global. We’ve made a lot of
progress on our, on our satellite system and concepts so
we’ve done performance analysis and rebuilding hardware in the lab right now we have
shown the technical feasibility we are now going to build a prototype
which is suitable for space and we could and then be ready to take it to
an actual space hardware. When IQC started in 2002 in Waterloo, really the focus was to build an institute focused on the
quantum science. We’ve established a reputation around
the world of doing this incredibly well. The next
step is to turn that science into technology, to develop the application
and the prototypes and the technology that comes out of the quantum science so
this is the part where we will focus in the next 10 years.

    its a shame this technology will only get the proper investment by parties backing "intelligence"agencies and the military and thus being developed and used for their goals
