Episode notes
Fundamentals of Quantum vs Classical Bits
- Quantum computing uses qubits that can exist in multiple states, unlike classical bits which are binary on or off.
- Quantum entanglement allows qubits to affect each other instantly, impacting cryptography and computation.
Quantum Computing's Unique Power
- Quantum computers solve complex problems by evaluating many possibilities simultaneously through qubits in superposition.
- They excel at fuzzy, high-variable problems like policy hardening, not straightforward arithmetic.
Personal Quantum Tech Journey
- Johna worked on free space lasers encoding bits during her undergrad and grad work in particle physics.
- She learned early quantum tech once thought useless is now foundational in quantum sensing and quantum key distribution.
