1Good afternoon, and welcome to the first lecture in our series on quantum computing.
2Today, I will explain the basic principles without going too deeply into the mathematics.
3A traditional computer stores information in bits, which are either zero or one.
4A quantum computer, by contrast, uses qubits, which can represent both values at once.
5This strange property is called superposition, and it is central to the whole field.
6Many people mistakenly think quantum computers are simply much faster versions of ordinary machines.
7In fact, they are only better for certain problems, such as simulating molecules for drug research.
8Let me give you a concrete example involving the design of new medical drugs.
9The first prototype was originally expected in June, but it appeared several months later.
10It was not the theory but the cooling equipment that caused most of the delay.
11What I want to emphasize today is that practical quantum computers remain extremely fragile.
12In our next session, we will examine how researchers are trying to correct quantum errors.
