10

8.2.1 Quantum Teleportation• History

– Energy, continuous or discrete?

– Infinite division? Oh NO!

– Uncertainty of Quantums• The more accurately an object is scanned, the more it is disturbed by

the scanning process, until one reaches a point where the object's original state has been completely disrupted, still without having extracted enough information to make a perfect replica.

• There might be so-called hidden variables that complete quantum mechanics

• Paper by Einstein, Podolsky, and Rosen stating a paradox in quantum mechanics, 1935

– Schrödinger’s cat

8.2.1 Quantum Teleportation

God does not play dice with theuniverse -Albert Einstein

Anyone who is not shocked by Quantum Theory has not understood it -Niels Bohr


13

8.2.1 Quantum Teleportation


14






– 8.2.3 Web 2.0




15

8.2.2 Internet of Things• The development of Internet based on Internet

• Concepts– Network of objects

– A system that would be able to instantaneously identify any kind of object

– Evolution from a network of interconnected computers to a network of interconnected objects

– From communicating people to communicating items

– From 3-5 computers per person to 10-25 communicating items per person

– From human triggered communication to event triggered communication


16

8.2.2 Internet of Things• Characteristics

– Pervasive• To be present throughout

– Ubiquitous• To be everywhere at the same time

– Emerging• Technology that emergences becomes more than “many single

instances of it”

• Do not yet know whereto the IoT “emerges”

– Global• All over the world

• Isolated solutions will not be successful


17

8.2.2 Internet of Things

• Key technologies and challenges– RFID

– Sensor

– Large-scale networking• NGN, IPv6, mobile IP

– Wireless communication• WPAN, WBAN, …

– Security


18

8.2.2 Internet of Things


19






– 8.2.3 Web 2.0




20

8.2.3 Web 2.0• The network as platform, spanning all connected

devices

• Web 2.0 – Delivering software as a continually-updated service that

gets better the more people use it

– Consuming and remixing data from multiple sources, including individual users, while providing their own data and services in a form that allows remixing by others

– Creating network effects through an "architecture of participation"

– Going beyond Web 1.0 to deliver rich user experiences
