abstract = {This is the first time in the 51-year history of the IFF
Spring School that the subject has been a “Technology”.
Can there be two weeks of intensive lectures by top
scientists on a mere technology? The decision just a few
years ago, to designate $\textbf{Quantum Technology}$ as a
coherent societal endeavour, was taken after much
deliberation within a large circle of working scientists.
This endeavour is not a technology in a traditional sense,
but is rather a unique intermingling of basic scientific
insights, new capabilities demonstrated in laboratories, and
an ambition to turn these unique capabilities into
applications for the further advancement of technical
capability on a number of fronts. The “quantum
revolution” has been declared multiple times over the last
century. The first uncovering of quantum mechanics at the
beginning of the 20$^{th}$ century was an intellectual
revolution, albeit a small one confined to the circle of
modern physicists. But by mid-century, quantum knowledge was
power: first with the quantum properties of the nucleus, but
much more extensively with the quantum behaviour of light
and of electrons, entirely new capabilities arose. This
first (quantum) technological revolution produced the
information processing world of today. But our second
quantum revolution, which has prompted the birth of our new
quantumtechnology era, was waiting to happen because only a
subset of the phenomena that are possible in the quantum
world were harnessed in the first edition. We have simple,
if inscrutable, names for some of these phenomena –
“quantum entanglement”, “spooky action at a
distance”, “quantum logic gates”. But it takes more
than a glance to perceive what are the new things that are
happening that produce our new quantum-technological era.
One helpful guide has been provided, and will be followed in
the lecture scheme of our two weeks together. We speak of
quantum technology as consisting of four pillars, which
define the new application areas that are foreseen as a
result of the fuller exploitation of the phenomenology of
the quantum world: $\textbf{Quantum Sensing and Metrology}$:
Quantum mechanics defines the smallest detectable influence;
here the aim is to produce detection devices working at this
limit. $\textbf{Quantum Communication}$: We can work towards
networks that communicate not bits, but two-level quantum
systems (qubits); these can yield absolute advantages in the
security, privacy, and authenticatability of transmissions,
and are important for interconnecting quantum computers:
$\textbf{Quantum Computing}$: If bits are replaced by qubits
in processors, a new style of computing machine can come
into being. For some problems it will have unrivalled
algorithmic power. $\textbf{Quantum Simulation}$: When
appropriately specialized, quantum processors can
efficiently mimic the dynamics of natural objects obeying
the laws of quantum mechanics. The quantum simulator can
sharpen our modelling abilities for complex molecular or
solid-state quantum systems. [...]},
