Working of Quantum Computer


As we know how Quantum computer are different from classical computer and they can't replace classical computer.
If haven't seen that blog. I recommend you to watch it before reading this blog for better understanding.Click Here

Quantum computer works on mainly three principle:
1.      Superposition.
2.      Entanglement.
3.      Interference.

1.Superposition: Superposition is one of the fundamental principles of Quantum Mechanic. It is a phenomenon were all possible configuration state are present during the process at the same time.

For Example: if I enter A & B as 2 bits input all possible state come under superposition i.e. 00,01,10,11.

2.Entanglement: The word tangle suggests that its connected. According to the principle of quantum mechanics entangle is the property in which two objects are connect with each other. As result if one object changes its value then automatically second object value gets change.

3.Interference: The process in which two or more wave of the same frequency combine to reinforce or cancel each other.

How it works?

When instruction is entered into the quantum computer qubit goes into superposition state where they can form all possible configuration, now by using the property of interference we control the quantum state and amplify the signal that are towards the right answer and cancel the type of signal that are leading to wrong answer. This is how Quantum computers uses the properties of quantum physics.

Secure Network(Week 4)

Network hardening is the process of securing a network by reducing its potential vulnerabilities through configuration changes and taking specific steps.   Implicit deny is a network security concept where anything not explicitly permitted or allowed should be denied. Analyzing logs is the practice of collecting logs from different networks and sometimes client devices on your network, then performing an automated analysis on them. Correlation analysis is the process of taking log data from different systems and matching events across the systems. Flood guards provide protection against Dos or denial of service attacks. EAP-TLS is an authentication type supported by EAP that uses TLS to provide mutual authentication of both the client and the authenticating server.   if you really want to lock down your network, you can implement 802.1x . DHCP Snooping Attack Why WEP Encryption fall apart? A general concept in security and encryption is to never send the plain ...

Authentication Authorization Accounting(week 3)

Identification is the idea of describing an entity uniquely. Biometric authentication is the process of using unique physiological characteristics of an individual to identify them. C.R.L(Certificate revocation list) :This is a signed list published by the CA which defines certificates that have been explicitly revoked. Lightweight Directory Access Protocol(LDAP): LDAP is an open industry-standard protocol for accessing and maintaining directory services. Authentication is related to verifying the identity a user, authorization pertains to describing what the user account has access to or doesn't have access to. An access control list or ACL , is a way of defining permissions or authorizations for objects.  RADIUS or Remote Authentication Dial-In User Service , is a protocol that provides AAA services for users on a network.It's a very common protocol used to manage access to internal networks, WiFi networks, email services and VPN services. when a client wants to access a r...

TCP Segment

A TCP segment is made up of a TCP header and a data section. Source Port :  A source port is a high numbered port chosen from a special section of ports known as ephemeral ports. A source port is needed so that when the web server replies, the computer making the original request can send this data to the program that was actually requesting it. It is in this way that when it web server responds to your requests to view a web page that this response gets received by your web browser and not your word processor. Destination Port : port on which the client in request the data( The destination port is the port of the service the traffic is intended for ) Sequence Number :This is a 32-bit number that's used to keep track of where in a sequence of TCP segments this one is expected to be.There are limits to the total size of what we send across the wire. In Ethernet frame, it's usually limited in size to 1,518 bytes, but we usually need to send way more data than that. At the transp...
