Quantum computing is a rapidly advancing field that is poised to revolutionize the technology landscape. By leveraging the principles of quantum mechanics, quantum computers are expected to vastly outclass their classical counterparts in tackling complex problems.

At the heart of a quantum computer are 'qubits'. Unlike traditional bits, which can either be 0 or 1, qubits can be both 0 and 1 at the same time, thanks to the principle of superposition. This means they can compute a vast number of calculations simultaneously, making them incredibly powerful.

Another key principle quantum computers leverage is entanglement. This refers to the concept that qubits in a quantum state can be entangled, whereby the state of one qubit can immediately affect the state of another, no matter the distance between them. This strange yet powerful property allows quantum computers to process information in a non-linear manner.

You may wonder what use such advanced and relatively abstract technology has in our everyday lives. The use-cases are endless. Quantum computers could fundamentally transform areas like cryptography, material and drug discovery, financial modeling, weather forecasting, and more.

In cryptography, for instance, quantum computers could disrupt current practices by breaking numerous encryption techniques currently considered secure. On a positive note, this also drives research into quantum encryption techniques, potentially propelling us into an era of unbreakable encryption.

Despite these promising advancements, quantum computing is still in its infancy, with numerous technical challenges to overcome. Quantum computer hardware is incredibly delicate, any sort of environmental noise can cause a 'quantum decoherence' disrupting computations. Moreover, quantum algorithms necessary to utilize this technology to its full potential are also at nascent stages.

With potential being boundless, quantum computing represents a new era of technology, which is expected to push the boundaries of what we previously considered mainstream and take us towards an unimaginably tech-advanced future.
