1、12Two things up front:First:Credit where due title art is from a usefully named bad 2010 TV movieNext:I will not be discussing this movie today,sorry!3Instead,Ill be discussing the intersection of quantum computing and cryptographyand maybe how to avoid ending up like this.Specifically:The rationale

2、 behind quantum computingWhy quantum computing impacts you todayThe intersection of quantum and cryptographyThe intersection of cryptography and businessBasic cryptographic conceptsMitigating quantum computings impactsWhat you can do today to quantum-proof your organization5Memorize that.Theres a qu

3、iz later.6Because quantum computing can turn your organizations future from this7To this.8No joke.9We call this“the coming Quantumpocalypse.”1011121314This allows operations to be done more quickly,and with less energy than classical computers.15(Example of a classical computer your smartphone.)Quan

4、tum computing uses the ability of subatomic particles to exist in more than one state at a time.In classical computers,a binary digit(bit)stores a single piece of information that can exist in one of two states:1 or 0.16Quantum computers use Quantum Bits-or Qubits.17Qubits are kind of like bits in t

5、hat there are two possible outcomes-a 0 or a 1.But also,not at all like bits,because the state of a Qubit can also be a superposition of both possible states.18Maybe its a 1,or maybe its a 0,or maybe its some combination of both at the same time.19Something like this:BITQUBITIn Quantum computing,thr

6、ee Qubits can represent all 8 values at once.20Example:In classical computing,three bits can represent any one of 8 values at a time:000,001,010,011,100,101,110,111.Takeaways:21A qubit stores much more information that a classical bitQuantum computers can perform operations much faster than a classi
