Why is maintaining coherence in quantum computing hardware crucial, and what challenges are associated with it?
Quantum computing represents a paradigm shift from classical computing by leveraging the principles of quantum mechanics to perform computations that would be infeasible or impossible with classical computers. One of the core concepts in quantum computing is the qubit, which, unlike a classical bit that can be either a 0 or a 1, can exist

What is the quantum coherent information and how is it related to conditional quantum entropy?
Quantum coherent information refers to the amount of information that can be reliably transmitted or stored in a quantum system while maintaining its coherence. In the field of quantum cryptography, coherence is a important property that ensures the security of quantum communication protocols. To understand the relationship between quantum coherent information and conditional quantum entropy,

What happens to macroscopic objects, like the needle, when they become entangled with a qubit?
When macroscopic objects, such as a needle, become entangled with a qubit, their properties become intertwined in a way that defies classical intuition. This phenomenon arises from the principles of quantum mechanics, which govern the behavior of particles at the microscopic level. Understanding the implications of entanglement between macroscopic objects and qubits requires delving into
