2
Do we understand quantum computing? This isn't right. It isn't even wrong. - Wolfgang Pauli, on a paper submitted by a physicist colleague

3
Quantum introduction ( very small ) Concepts Superposition Entanglement observer effect Qubit If someone says that he can think or talk about quantum physics without becoming dizzy, that shows only that he has not understood anything whatever about it. Niels Bohr

4
Quantum Computing (1) Quantum computer quantum tech, traditional operation smaller, faster quantum size range Turing universal computer irreversible computations

5
Quantum Computing (2) Quantum cryptography photon polarization angular polarization detector angle public exchange of angle but not value photon entanglement eavesdropping detection

6
Quantum Computing (3) Quantum computing computing device or processor analogue computer not digital?

7
Analogue Computers Spaghetti computing parallel sorting special purpose/application Slide rule exact computation imprecise reading Adiabatic quantum computer least energy = best answer least path, best comparison, simulation D-Wave Orion

8
Applications and Implications by domain general functions least path Traveling Salesman Problem scheduling, efficiency studies, multiple requirements NP-complete, non-convergent, Ising model simulation climate models pattern recognition people are good, computers are bad data reduction and representation

9
Security management risk management (shortest path) what if - cost vs benefit information classification (pattern matching) risk assessment required investing, or not, in quantum computing

10
Security architecture new architectures, new vulnerabilities simulation of vulnerabilities and protections quantum devices and noise D-Wave Orion voting, error checking quantum error correction (recent) fault tolerant computing

11
Access control biometrics (pattern matching) information flow and covert channel analysis (least path/simulation) intrusion detection (pattern matching)

12
Cryptography quantum communications/encryption/key negotiation/eavesdropping detection parallel decryption new algorithms tractable by neither classical nor quantum quantum devices and generation of randomness analysis of implementation problems (simulation)

13
Physical noise, RFI/EMI interference temperature room temp 100x > interstellar space interstellar space 1000x > Orion device special costs, protections for devices physical access control (biometrics)

14
BCP Business Impact Analysis (least path) testing of BC plans (simulation) disaster management direction of resources to maximum effect continuity of operations for special devices damage if power/cooling fails

15
Applications security testing (simulation) database analysis (pattern matching) cost (privacy) vs benefit (safety) database aggregation problem analysis (pattern matching and simulation) learning (pattern matching) neural net augmented, check against neural net superstitious learning check against expected impossible to compute by classical methods malware/botnet detection, (pattern matching) operation/control/ownership completely new paradigms in programming

16
Operations security combinations of classical and quantum devices and operations complexity, troubleshooting troubleshooting (simulation) insider attack detection (pattern matching)

17
Telecommunications and networking Intrusion Detection Systems Botnet detection and assessment Command & Control ownership fast flux Network attack analysis quantum encryption special channels quantum devices likely remote access

18
Telecommunications and networking Spam limitations even in Bayesian analysis

19
Telecommunications and networking quantum encryption requires special channels quantum devices likely to be remote access

20
Law and investigation new forensic analysis tools (pattern matching/simulation) presentation/acceptance in court problematic
